What is stainless steel 321 Fastener?

Stainless Steel 321 Fastener is a type of bolt that is made out of stainless steel and is 1/4 long. The head of the bolt has a pan head style and is 1/2 in diameter. Four slots in the head allow it to be attached to a bolt. The threads are coarse threads with an ISO standard size of M3x0.5mm and are threaded down the steel bolt to the end of the fastener, where there is a flat spot for driving into material with a tool such as an Allen wrench or socket wrench.

How Long Does Stainless Steel Fastener Last?

Grade 321 fasteners can last for years, depending on the type of material it is being fastened to and the intensity of use. 321 SS fasteners can last for decades if adequately cared for and maintained. When a 321 SS Hex Bolt is used in a low-use situation, it could last as long as 15 years or more before needing to be replaced. In high-use conditions where 321 Stud bolts are constantly tightened and loosened, the life of the buckle can be cut to only three years or less before needing to be replaced.

How to Install Stainless Steel 321 Fastener?

Installing the fasteners is simple. You need to measure the hole carefully with a caliper, then drill it at least 1/4th smaller than the size of the Steel bolt you’re using. Tap it gently with a hammer to ensure it becomes an even surface for insertion. You will insert one side, apply some liquid lubricant to aid in turning, and tighten by hand before turning on your power drill. With this done, you can repeat this process with your other set side.
