187-7738 3.5 mm Thick Flat Hard Washer
Flat Plate
Description
evenly distributes the load and prevents surface damage during the process Description:
Cat® fastener parts are designed for specific applications based on size, strength, clamp load and past performance. This is 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.
Features
- Cat fasteners are manufactured to strict specifications for durability, reliability and efficiency
High • Strength and Quality – Fasteners meet or exceed ISO, ASTM, ASME and SAE requirements.
- Cat bolts, together with the associated hardened washers and nuts, form a high-performance system that produces sustained high clamping force.
- Coating meets the special requirements of different applications (RoHS compliant).
Applications
Cat bolts and their associated washers and nuts form a high-performance system that provides consistent, high clamping force. You can trust Cat fasteners to help you build, maintain or rebuild in most machine and shop applications worldwide.
