176-2543 5/8″-11 x 1 3/4″ 12-Point Head Bolt
12-Point Head Bolt
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 bolts are commonly used in engines and driveline. 12-point head bolts have high fatigue performance and fit designs that do not have enough clearance for hex head bolts.
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.
