Value Collection R63091446 Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R63091446 is a 1/4-20 x 1/2 inch hex head cap screw manufactured from brass. It features a unified national coarse (UNC) thread standard and a 7/16 inch hex drive. The 1/2 inch dimension reflects the length under the head. Brass construction offers natural corrosion resistance and is well suited for applications where galvanic compatibility with copper or bronze components is required. This fastener is commonly installed by plumbers, HVAC technicians, electricians, and general mechanical trades working with brass fittings, valve bodies, electrical enclosures, and light structural assemblies.

This screw is appropriate for residential and light commercial applications where a non-sparking, corrosion-resistant fastener is needed. Typical uses include securing brass valve covers, terminal blocks, panel components, and equipment housings. The UNC thread form is the most widely used inch-series thread standard in North America, making this screw compatible with the majority of standard tapped holes of the same diameter and pitch in brass, bronze, and softer metal assemblies.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard inch-series tapped holes
• 1/2 inch length under head for low-profile fastening applications
• Brass material provides corrosion resistance and galvanic compatibility with copper and bronze components
• 7/16 inch hex head for standard wrench or socket installation
• Non-sparking brass construction suitable for use near flammable gases or vapors

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 1/4-20 UNC threaded fastener in brass construction.

Installation Notes

This fastener is installed using a 7/16 inch open-end wrench, combination wrench, or socket. De-energize any electrical equipment and isolate any pressurized system before replacing fasteners on live assemblies. Brass is a softer material than steel — avoid over-torquing, as thread stripping is more likely than with ferrous fasteners. Follow applicable mechanical codes for fastener torque and assembly requirements specific to the equipment being serviced.
