Value Collection R68449442 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R68449442 is a hex socket cap screw designed for secure, high-torque fastening in demanding industrial and trade applications. It features a 5/8-11 UNC thread size and a 2.25-inch length under head, providing substantial thread engagement for structural and mechanical assemblies. The fastener is driven by a 0.5-inch hex key or Allen wrench, allowing access in recessed or tight-clearance locations where a standard hex head wrench cannot reach. Constructed from 18-8 stainless steel, it resists corrosion in wet, outdoor, and chemically exposed environments. This screw is appropriate for use by millwrights, pipefitters, mechanical contractors, and maintenance technicians.

This hex socket cap screw is suited for use in general mechanical assemblies, machinery mounting, pipe supports, brackets, and structural connections where corrosion resistance is required. The 5/8-11 UNC coarse thread pattern is common in standard U.S. mechanical and industrial equipment. It is appropriate for both indoor and outdoor installations where stainless steel fasteners are specified, including food-processing environments, marine-adjacent applications, and chemical plant facilities.

Key Features

• 5/8-11 UNC coarse thread for standard U.S. mechanical fitment
• 2.25-inch length under head provides deep thread engagement
• 0.5-inch hex drive allows installation in recessed or confined spaces
• 18-8 stainless steel construction resists corrosion and oxidation
• Socket cap head profile keeps a low, clean profile in finished assemblies

Compatibility

Designed as a standard 5/8-11 UNC hex socket cap screw for use in any application specifying a coarse-thread stainless steel socket cap fastener of this thread size and length.

Installation Notes

Installation requires a 0.5-inch hex key or Allen-style driver; use a calibrated torque wrench when torque specifications are called out in the equipment service documentation. Ensure the mating threaded hole or nut is clean and free of debris before driving. Stainless steel fasteners are susceptible to galling under high-speed installation — apply an anti-seize compound when specified. Follow applicable ASME or equipment OEM fastener standards for proper seating.
