188-9644 25 mm Long Flat Head Screw

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.

Used where the clearance between parts is important so that the parts fit together tightly.

Features

Cat fasteners are manufactured to precise specifications for durability, reliability and high 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.
Coating meets 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.
