Value Collection R68449480 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R68449480 is a hex socket cap screw designed for industrial, mechanical, and structural fastening applications. It features a 5/8-11 UNC thread size and measures 3 inches in length under the head. Drive engagement is through a 1/2-inch internal hex (Allen) socket. The fastener is manufactured from 18-8 stainless steel, providing corrosion resistance in wet, outdoor, and chemically exposed environments. Machinists, maintenance mechanics, pipefitters, and general contractors install this type of fastener where a flush or recessed cap head profile is required and hex key access is available.

This screw is suited for equipment assemblies, machinery frames, brackets, and structural connections where 5/8-11 UNC threading is specified. The 18-8 stainless steel construction makes it appropriate for food-service equipment, marine environments, plumbing equipment, and outdoor installations where carbon steel hardware would corrode. The coarse 11-thread-per-inch pitch provides reliable engagement in a wide range of base materials including steel, aluminum, and engineered plastics.

Key Features

• 5/8-11 UNC coarse thread for broad material compatibility and fast engagement
• 3-inch length under head accommodates thick material stacks
• 1/2-inch internal hex drive allows torque application with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• Cap head profile sits flush to slightly recessed, reducing snag hazards in finished assemblies

Compatibility

Designed as a standard 5/8-11 UNC hex socket cap screw for use in any application calling for this thread size and a 1/2-inch hex drive fastener in 18-8 stainless steel.

Installation Notes

Install using a 1/2-inch hex key, T-handle, or hex bit socket driver. Ensure mating threads are clean and free of debris before installation. For critical structural or pressure-bearing joints, consult applicable torque specifications from the equipment manufacturer or relevant standards. Stainless steel fasteners are susceptible to galling during installation — applying an anti-seize compound to the threads is standard practice to prevent thread damage.
