Value Collection R57001260 Hex Cap Screw 9/16-12 X 4 in 18-8 Ss

Product Description

The VALUE COLLECTION R57001260 is a 9/16-12 x 4-inch hex head cap screw manufactured from 18-8 stainless steel with an uncoated finish and partial threading along the shank. The fastener follows Unified National Coarse (UNC) thread standards and is measured length-under-head, giving installers a consistent reference for bolt engagement depth. The 18-8 stainless steel construction provides solid corrosion resistance in wet, chemical-exposed, or outdoor environments. Mechanical, plumbing, HVAC, and electrical trades use this type of fastener wherever a standard hex-drive, corrosion-resistant cap screw is required for structural or equipment-mounting applications.

This cap screw is suited for general industrial and trade applications including equipment frames, pipe hangers, duct supports, panel mounting, and similar structural connections. The partial thread design allows the unthreaded shank to align mating components before the threaded section engages, which is useful in close-tolerance assemblies. It is appropriate for both indoor and outdoor installations where stainless steel fasteners are specified for longevity and resistance to rust or galvanic corrosion in mixed-metal assemblies.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• 9/16-12 UNC thread size with partial threading for improved shank alignment during installation
• 4-inch length measured under head for consistent engagement depth reference
• Uncoated finish — no risk of coating interference with torque values or thread fit
• Hex head drive accepts standard hex sockets and wrenches common on job sites

Compatibility

Designed as a standard UNC hex head cap screw for general trade and industrial fastening applications requiring a 9/16-12 thread and 4-inch length-under-head dimension in 18-8 stainless steel.

Installation Notes

Install using a properly sized hex socket or open-end wrench; do not use pliers or pipe wrenches on the hex head, as this can damage the drive surface. De-energize or depressurize any equipment before removing or replacing structural fasteners. Apply anti-seize compound if mating material is also stainless steel to prevent galling during tightening. Follow applicable codes and equipment manufacturer torque specifications for the joint being assembled.
