Fractional 18-8 Stainless Steel Nylon Insert Thin and Standard Hex Locknut

Fractional 18-8 Stainless Steel Nylon Insert Locknuts

Thin and Standard Hex Fastening Solutions for Reliable Vibration Resistance

Fractional 18-8 stainless steel nylon insert locknuts, available in thin (jam) and standard hex styles, provide dependable locking performance combined with excellent corrosion resistance. Commonly used in general industrial, construction, and maintenance applications, these locknuts prevent loosening caused by vibration while maintaining clean thread engagement and long service life.

18-8 Stainless Steel Construction

Strength and Corrosion Resistance for Everyday Use

18-8 stainless steel (Type 304) offers a strong balance of mechanical strength and corrosion resistance, making it suitable for indoor and outdoor environments. These locknuts resist rust, oxidation, and staining, ensuring consistent performance in humid, mildly corrosive, or washdown conditions.

Nylon Insert Locking Action

Secure Hold Without Damaging Threads

Each locknut features a nylon insert (nyloc® style) that creates prevailing torque when engaged with a bolt. The insert grips the threads to resist vibration-induced loosening while protecting the mating fastener from galling. This design allows for easy installation and removal, making the locknuts reusable in many applications.

Thin (Jam) Hex Locknuts

Low-Profile Locking in Tight Spaces

Thin hex nylon insert locknuts are ideal where clearance is limited or where a secondary locking nut is required. Their reduced height helps minimize stack-up while still providing effective vibration resistance.

Standard Hex Locknuts

Full-Height Locking for General Applications

Standard hex 18-8 stainless steel nylon insert locknuts provide maximum thread engagement and holding strength. They are widely used in structural assemblies, machinery, and equipment where reliable, long-term fastening is required.

Fractional Thread Sizes

Compatibility with Standard Inch Hardware

Available in a wide range of fractional thread sizes, these locknuts pair easily with standard inch-series bolts and threaded rods, simplifying inventory and maintenance.

Typical Applications

• Industrial machinery and equipment

• Construction and building hardware

• Electrical enclosures and panels

• HVAC systems

• General MRO and fabrication

For cost-effective, corrosion-resistant fastening with reliable vibration control, fractional 18-8 stainless steel nylon insert thin and standard hex locknuts deliver trusted performance across countless applications.
