179-4324 M5 x 0.8 mm Hex Lock Nut
Nylon Insert Locknut
Description
Cat® fastener parts are designed for specific applications based on size, strength, clamp load and past performance, information other manufacturers do not have. They are carefully selected to last until machine rebuild or end of life. Non-Cat hardware and fasteners may appear to fit your machine, but no one else knows your equipment the way we do.
These nuts provide prevailing torque so the nuts will not loosen. Do not exceed 120 C.
Features
*Cat fasteners are manufactured to precise specifications for durability, reliability and efficiency
* Strength and quality – fasteners meet or exceed ISO, ASTM, ASME and SAE requirements.
* Cat bolts, nuts and washers are specifically designed to work together as a system to maximize clamping force.
* Coatings meet the special requirements of different applications (RoHS compliant).
Applications
Cat bolts form a high-performance system with mating hardened washers and nuts to produce consistent, high clamping force. You can trust Cat fasteners to help you build, maintain or rebuild in most machine and shop applications worldwide.
