Value Collection 208997B Hex Head Cap Screw 5/8-11 2-3/4 in

Product Description

The VALUE COLLECTION 208997B is a hex head cap screw designed for general fastening applications across mechanical, structural, and industrial assembly work. It features a 5/8-11 thread size with Unified National Coarse (UNC) threading and a 2-3/4 inch length under head. Constructed from 18-8 stainless steel, this fastener provides reliable corrosion resistance in wet, outdoor, and chemically exposed environments. The 15/16 inch hex drive accepts standard hex sockets and wrenches. This screw is suited for use by millwrights, maintenance technicians, pipefitters, and general tradespeople who require a durable stainless fastener in inch-standard sizing.

This hex head cap screw is appropriate for residential and commercial applications where corrosion resistance is a priority. Common install scenarios include outdoor structural connections, plumbing support brackets, HVAC equipment mounting, pool and water treatment equipment, and marine-adjacent environments. The 18-8 stainless steel grade resists rust and oxidation in humid or wet conditions, making it a practical choice over plain steel or zinc-plated alternatives in exposed installations.

Installation Notes

Installation is performed by the responsible trade technician using a 15/16 inch socket or combination wrench. Always verify thread engagement depth and ensure mating threads are clean and free of debris before driving. Do not mix stainless steel fasteners with dissimilar metals in applications where galvanic corrosion is a concern. Follow applicable mechanical and structural codes for torque and fastener specifications relevant to the specific assembly.
