Value Collection 207759 Hex Head Cap Screw 5/8-11 X 1-1/2 in

Product Description

The VALUE COLLECTION 207759 is a hex head cap screw in 5/8-11 thread size and 1-1/2 inches length under head, manufactured from 18-8 stainless steel. The 18-8 grade designation indicates an austenitic stainless alloy with approximately 18 percent chromium and 8 percent nickel, offering solid corrosion resistance for general industrial and mechanical applications. The thread specification is 5/8-11 UNC (Unified National Coarse), driven with a 15/16-inch hex wrench or socket. This fastener is installed by millwrights, maintenance technicians, pipefitters, and general tradespeople wherever a corrosion-resistant hex cap screw is required.

This screw is suited for structural and mechanical assemblies in environments where moisture, mild chemicals, or outdoor exposure make carbon steel fasteners a poor choice. Typical applications include equipment mounting, pipe flange connections, pump housings, and general fabrication work where 18-8 stainless is an accepted material specification. The UNC thread form is compatible with standard inch-series tapped holes and hex nuts at 5/8-11 pitch.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and mildly corrosive environments
• 5/8-11 UNC thread for compatibility with standard inch-series tapped holes and nuts
• 1-1/2 inches length under head for typical through-bolt and tapped-hole applications
• 15/16-inch hex drive accepts standard sockets and open-end wrenches
• Inch measurement system throughout — no metric conversion required

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application calling for a 5/8-11 UNC fastener in 18-8 stainless steel.

Installation Notes

Install with a 15/16-inch socket, box-end, or open-end wrench. De-energize and lock out any equipment before fastener service per applicable OSHA lockout/tagout procedures. Apply anti-seize compound when installing stainless fasteners into stainless or aluminum tapped holes to prevent galling. Do not use impact tools without a torque-limiting mechanism, as 18-8 stainless is susceptible to galling under high rotational speed.
