OVERVIEW

Technical Specification

The ESAB 636250 is a precision-engineered fastening component designed for industrial MRO applications. This locknut utilizes a nylon insert (commonly referred to as a Nyloc nut) which acts as a prevailing torque mechanism. As the bolt threads engage the nylon ring, the friction increases significantly, creating a radial compressive force that locks the nut in place. This design is critical for assemblies subject to dynamic loads, preventing the fastener from backing off due to vibration or thermal cycling.

Material and Dimensions

Manufactured from high-grade stainless steel (SS), this component provides excellent resistance to oxidation and corrosion, making it suitable for use in harsh shop environments where exposure to moisture, fumes, or chemicals is common. The thread specification is .312-24, which corresponds to a 5/16-inch nominal diameter with a fine thread pitch of 24 threads per inch (UNF). Fine threads provide greater tensile strength and finer adjustment capabilities compared to coarse threads, ensuring a secure and precise fit for critical equipment assemblies.

FAQ

The thread size is .312-24, which is equivalent to 5/16-24 UNF (Unified Fine thread).

Yes, it is manufactured from stainless steel (SS) for corrosion resistance.

The nylon insert creates friction against the bolt threads to prevent the nut from loosening due to vibration.

While it can be physically reused, it is recommended to replace nylon insert locknuts after removal as the nylon's locking ability degrades.

Yes, this is a genuine ESAB replacement part, SKU 636250.

No, this is a fine thread (24 TPI) nut. It will not fit a standard 5/16-18 coarse thread bolt.
