Value Collection 207559B Hex Head Cap Screw 1/4-20 X 7/8 in

Product Description

The VALUE COLLECTION 207559B is a 1/4-20 hex head cap screw machined from 18-8 stainless steel. It measures 7/8 inches under the head with a Unified National Coarse (UNC) thread form and a 7/16-inch hex drive. The 18-8 stainless alloy provides solid corrosion resistance in wet, outdoor, and chemically active environments without sacrificing tensile strength. This fastener is installed by mechanics, millwrights, plumbers, HVAC technicians, and electricians wherever a standard 1/4-20 inch threaded connection is required and corrosion resistance is a priority.

This screw is suited for general mechanical assembly, equipment mounting, panel fastening, and structural connections in residential and light commercial applications. It fits any application calling for a 1/4-20 UNC thread in inch-measurement systems. The hex drive accepts standard SAE wrenches and sockets, making it practical across a wide range of trade installations including HVAC equipment mounting, plumbing fixture supports, and electrical enclosure assembly.

Key Features

• 18-8 stainless steel construction resists corrosion and oxidation in damp or outdoor service environments
• 1/4-20 UNC thread for compatibility with standard inch-system tapped holes and nuts
• 7/8-inch length under head suits shallow to mid-depth fastening applications
• 7/16-inch hex drive accepts standard SAE wrenches and sockets
• Inch measurement system consistent with North American trade and equipment standards

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw for use in any inch-thread application requiring an 18-8 stainless steel fastener of this length and drive size.

Installation Notes

Installation requires a 7/16-inch wrench or socket. Power down or de-energize any equipment before fastening near electrical components, and shut off fluid systems before working on plumbing or HVAC assemblies. Follow applicable codes such as the NEC or IFGC for equipment mounting requirements. Do not overtighten stainless fasteners, as galling can occur without lubrication on the thread flanks.
