Value Collection R63091882 Hex Head Cap Screw Brass

Product Description

The VALUE COLLECTION R63091882 is a hex head cap screw designed for general fastening applications in mechanical, plumbing, HVAC, and light industrial assemblies. Machined to Unified National Coarse (UNC) thread standards, this screw features a 3/8-16 thread size and a 3/4 inch length under head. The 9/16 inch hex drive head is compatible with standard hex wrenches and sockets. Constructed from solid brass, it offers natural corrosion resistance without surface coatings, making it suitable for environments where ferrous fasteners are not appropriate. Licensed tradespeople and experienced technicians use this type of fastener when material compatibility or conductivity concerns rule out steel hardware.

This screw is appropriate for use in residential and light commercial installations where brass fasteners are specified. Common applications include plumbing fixture mounting, electrical panel grounding hardware, HVAC equipment enclosures, and pool or spa equipment assemblies where moisture exposure is a factor. Brass UNC fasteners are also used in situations requiring non-magnetic or low-corrosion hardware. This part is sold individually but is subject to a minimum order quantity of 5 units.

Key Features

• 3/8-16 UNC thread form for broad compatibility with standard tapped holes
• 3/4 inch length under head suits shallow through-hole and tapped applications
• Solid brass construction provides corrosion resistance without plating
• 9/16 inch hex head drives with standard wrenches and sockets
• Inch measurement system with UNC thread standard

Compatibility

Designed as a standard UNC hex head cap screw for use in any application specifying a 3/8-16 brass fastener with a 3/4 inch length under head and a 9/16 inch hex drive.

Installation Notes

Install with a 9/16 inch open-end wrench, box wrench, or socket. De-energize and depressurize the assembly before fastener replacement in live mechanical or electrical systems. Brass is a softer material than steel — avoid overtightening, which can strip threads or deform the head. Follow applicable codes such as NEC or IPC when using fasteners in electrical or plumbing assemblies.
