Product Identity

MIDWEST FASTENER CORP 68487 is a 1/4"-28 nylon insert lock nut made from 18-8 stainless steel. It is designed for fastening tasks where vibration or torque would loosen a standard nut. The nylon insert creates prevailing torque to keep the assembly secure.

Who It Suits

Mechanics and builders who need a reusable locking fastener for 1/4"-28 threads in corrosive environments will find this part fits the requirement. Buyers who require a different thread pitch, a larger diameter, or a non-locking hex nut should look at other options.

Deciding Specification

The 1/4"-28 thread size is the single detail that determines whether this nut matches the bolt or stud in your assembly. Verify the thread pitch before ordering to ensure compatibility.

Questions about this item

How does the 1/4"-28 thread pitch perform on a stainless steel lock nut?

The fine 28 threads per inch provide a tighter grip and better vibration resistance than coarse threads on the same diameter.

What does the 18-8 stainless steel designation tell me about corrosion resistance?

18-8 stainless contains roughly 18 percent chromium and 8 percent nickel, giving strong resistance to rust and chemical attack in most environments.

What physical clearance is needed for the nylon insert lock nut?

The nut height includes the nylon insert, so allow enough bolt length for full thread engagement past the insert.
