Value Collection R63008442 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R63008442 is a hex socket cap screw designed for secure, high-torque fastening in demanding industrial and mechanical applications. The fastener features a 5/8-11 UNC thread size and a 2-inch length under head, providing substantial clamping depth for thick-section assemblies. Drive engagement is via a 1/2-inch internal hex socket, which allows a high torque input with a standard Allen or hex key. Constructed from Grade 316 stainless steel, this screw resists corrosion in wet, marine, chemical, and outdoor environments. Machinists, millwrights, maintenance technicians, and pipefitters regularly specify this fastener type where both strength and corrosion resistance are required.

This screw is suited for use in equipment assembly, structural fixturing, pump and valve mounting, and general mechanical maintenance where a low-profile cap head is preferred over a hex bolt. The 5/8-11 UNC thread is a coarse-pitch designation standard across North American tooling and equipment. Grade 316 stainless steel makes this fastener a reliable choice in food processing, marine, chemical processing, and wastewater environments where standard carbon steel fasteners would corrode prematurely.

Key Features

• 5/8-11 UNC coarse thread for compatibility with standard North American tapped holes and nuts
• 2-inch length under head provides substantial grip length for thick-section joints
• 1/2-inch internal hex socket drive for high-torque application with Allen keys or hex-socket drivers
• Grade 316 stainless steel construction offers superior corrosion resistance compared to 304 stainless
• Low-profile socket cap head design allows installation in recessed or counter-bored clearance holes

Compatibility

Designed as a standard-dimension hex socket cap screw for use in any application requiring a 5/8-11 UNC threaded fastener with a 2-inch length under head and 1/2-inch hex drive.

Installation Notes

Install using a 1/2-inch hex key, T-handle Allen wrench, or a hex-socket bit rated for the drive size. Verify that the mating tapped hole is clean, free of debris, and cut to 5/8-11 UNC specification before threading the screw. Apply appropriate anti-seize compound when installing 316 stainless fasteners into stainless tapped holes to prevent galling. Always torque to the fastener specification appropriate for the joint design and material; do not over-torque stainless steel fasteners, as the material is more susceptible to shear than hardened steel grades.
