Washer Manufacturer | F436 Fasteners: Complete Guide for Manufacturers, Suppliers, and Buyers

In the world of fastening solutions, washers play a crucial role in ensuring the stability, longevity, and integrity of assemblies. These small but essential components distribute load, prevent loosening, and protect surfaces from damage. From industrial machinery to household appliances, washers are indispensable.

Introduction to Washers

Washers are thin plates (typically disk-shaped) with a hole in the middle that is used to distribute the load of a threaded fastener, such as a bolt or nut. They serve multiple functions:

Load Distribution: Preventing localized stress on surfaces.

Vibration Absorption: Minimizing loosening due to vibrations.

Sealing: Preventing leakage in fluid systems.

Spacing: Adjusting the gap between components.

Depending on the application, washers can be made from various materials, including mild steel (MS), stainless steel (SS), brass, copper, and high-nickel alloys.

Introduction to F436 Washer

F436 fasteners primarily consist of hardened steel washers manufactured in accordance with the ASTM F436 specification. These fasteners are designed to be used with structural bolts, nuts, and assemblies, particularly in high-strength structural connections. The ASTM F436 standard ensures the washers are capable of handling the heavy loads and environmental conditions encountered in structural steel construction, bridges, towers, buildings, and other critical infrastructure.

The unique properties of F436 fasteners, especially washers, include excellent hardness, strength, and resistance to deformation under load, making them an essential component in high-strength bolted connections.

What are ASTM F436 Washers?

ASTM F436 is a standard that defines the chemical, mechanical, and dimensional specifications for hardened steel washers designed for use with:

ASTM A325 (now ASTM F3125) structural bolts

ASTM A490 (now ASTM F3125) structural bolts

Other high-strength bolted assemblies

They are typically flat washers that help distribute the load evenly and protect the mating surfaces from damage due to tightening torque and dynamic loads.

Types of F436 Fasteners

While ASTM F436 specifically covers washers, many people often refer to "F436 fasteners" to describe the broader assembly they're part of. Below are common F436 fastener components:

1. F436 Hardened Washers

F436 Type 1: Hardened washers manufactured from standard carbon steel, providing high strength and durability.

F436 Type 3: Hardened washers produced from weathering steel, offering superior corrosion resistance, ideal for outdoor and exposed applications.

Coated F436 Washers: Including zinc-plated, hot-dip galvanized, mechanical galvanized, and others for corrosion protection.

2. F436 Assembly Components

Though technically not part of ASTM F436, these are typically used with F436 washers:

Structural Bolts (ASTM F3125 A325 or A490)

Heavy Hex Nuts (ASTM A563)

Tension Control Bolts

Anchor Bolts

Applications of F436 Fasteners

F436 washers and associated fasteners are widely used in industries that demand strong, durable, and reliable connections, such as:

The World Zoonoses Day (July 6) holds significance in the wake of the novel coronavirus disease (COVID-19) pandemic, believed to have been originated in bats and transmitted to humans via pangolins. There have been periodic emergence and re-emergence of zoonotic diseases such as Severe Acute Respiratory Syndrome, Middle East Respiratory Syndrome and Ebola in the past. Zoonosis is an infectious disease caused by a pathogen that originated in animals but jumped to humans directly or through an intermediary species. Animals have therefore played an essential role in maintaining zoonotic infections — bacterial, viral or parasitic —  in nature .

[tsaritza-mika]

The Main 6 Enjoying Lush

Gonna put a small disclaimer of sorts here XDDD I don’t work for Lush, I just love their products, and feel they’re pretty great. Okay, end disclaimer

Asra 

Hair: Avocado shampoo/conditioner bar, New shampoo, Curl Power hair cream, and Jasmine and Henna hair treatment

Body: Let The Good Times Roll face and body cleanser, Intergalactic bath bomb

Face and Lips: Don’t Look at Me face mask and Unicorn lip scrub

Always says ‘hi’ to everyone working that day, they all know him and wait for the next time comes back to share new travel stories

Buys at least two of everything to last longer since he’s always planning for his next destination

Loves it when he can just take a day for himself and relax w/ Faust, but doesn’t do it as often as people may think

Nadia

Hair: Angel Hair shampoo bar and Power conditioner

Body: Goddess bar, Sticky Dates or Sleepy shower gel, Sex Bomb bath bomb, Cosmetic Lad moisturizer, and Therapy massage bar

Face and Lips: Brush Strokes face mask, Imperialis face moisturizer and Rose Lollipop lip balm

Usually comes in on her way home from work, or just orders online. She’s a busy woman, so she doesn’t always have time to do things in person

Will sometimes have joint spa days w/ Portia if they’re both free

Also has speakers in her massive bathroom to play either soothing tropical sounds or soft, relaxing music

Julian

Hair: Flyaway Hair shampoo bar, Big conditioner bar/cream conditioner, and Revive hair treatment

Body: Outback bar soap, Cup ‘o’ Coffee face and body scrub, and Black Rose bath bomb

Face and Lips: Cup ‘o’ Coffee face mask, Cookie Dough lip scrub

Portia introduced him to the shop, and the staff was so patient and nice, he can’t help but always want to go back. Totally gets flustered when they remember him

Will consider trying something new each visit. He likes to know all of his options

The first time he used everything, he swore he could hear himself squeak with how clean he felt. Also got so very flustered with how many people commented on how good he smelled. Total confidence booster XDDD

Portia

Hair: Seanik shampoo bar, The Golden Cap conditioner bar, and Super Milk hair primer

Body: What’s Up Doc? shower gel, and Gummy Bear shower jelly, and Toby’s Magic Cow bath bomb

Face and Lips: Cosmetic Warrior face mask and Carrot Stick lip oil

Came across the shop while out shopping, and now swears by it

Fell in love with how much they had for curly, bouncy hair

Is known by name at her local store, and also knows everyone who works there

Muriel

Hair: Soak and Float shampoo bar and Glory conditioner

Body: Whoosh shower jelly, Dirty Springwash shower gel, Aloe Bamboo cleanser roll, and Lakes bath bomb

Lips: None of Your Beeswax lip balm

Asra dragged him along after going with Portia on a previous run

Felt more than a little overwhelmed by all the options, but the person who ended up helping him was really nice about keeping his personal bubble, so it wasn’t so bad

Glad that he could have the website remember his previous order and he could just get more whenever he’s out. Doesn’t change his orders very often, but sometimes the holiday stuff is good

Lucio 

Hair: Daddy-O shampoo and Candy Rain conditioner, Marilyn hair treatment, and Infra Wig hair gel

Body: Mimosa shower gel for the rest of the year, Yog Nog used with Rose Jam for the holidays, Conga shower jelly, and Each Peach (And Two’s a Pair) massage bar

Face and Lips: Catastrophe Cosmetic face mask, Cucumber eye pads, and Hot Lips lip mask and scrub

Was totally turning his nose up at the unassuming shop front at first. Why would he shop at a place that didn’t even have a gold sign? Then he stepped inside...

Spends way too much money because he uses practically everything daily, but the palace staff doesn’t mind because at least that means he smells far better than with the cheap crap he used to use (sorry not sorry Axe lovers XDDDD)

Also buys the makeup, but will tell others that he still uses the $300-$400 stuff. It’s his best beauty secret

i was thinking about hc’s the other day so i’m deciding to post some! these are very random and in no way following a specific story or blurb :)

♡︎ i like to think Emily is a fiend when it comes to buying body care products. Like it's her guilty pleasure type thing. She’ll go to the mall and pass a Bath and Body Works and she won’t be able to resist. I think she like the Coconut Pineapple scented body wash they have rn. I think she buys the team random body mists, hand sanitizers, and soaps just because!

♡︎ Derek "tough guy" Morgan cried at Hamilton when he watched it on Disney+ with Savanah. He makes her promise not to tell the team. ESPECIALLY Garcia. (it ends up slipping out one night at Rossi's and he never lives it down)

♡︎ i think Spencer really likes skincare products and Lush, but he can’t be in there for too long bc there's too many strong smells :( i like to think he really likes the earthy scents like Rad Dad, Dirty Springwash, and the Cup of Coffee face mask. He also has one of the face roller things in Jade

♡︎ the lovely Penelope Garcia listens to Kim Drac and LOVES them. She listens to Paparazzi at least 3 times a day

♡︎ JJ has gone headfirst into being a suburban mom, but only during Fall. White Woman Autumn is her favorite season, pumpkin spiced lattes are her favorite Starbucks drink, and her wardrobe only consists of skinny jeans with oversized cashmere sweaters and knee-high brown boots. She's basic, but she's very aware of that

I'll do a part two with Tara, Matt, Luke and Kate if people like this :)
