Value Collection 30734 Hex Head Cap Screw 1/4-20 X 1-1/2 in

Product Description

The VALUE COLLECTION 30734 is a 1/4-20 UNC hex head cap screw machined from silicon bronze, sold in a 25-piece pack. Silicon bronze offers strong corrosion resistance in wet and marine environments, making this fastener a practical choice where stainless or zinc-plated hardware falls short. The screw measures 1-1/2 inches under the head with a 7/16-inch hex drive. Thread standard is Unified National Coarse (UNC), the most common inch-series thread form. These are turned with a standard 7/16-inch hex wrench or socket. Plumbers, pipefitters, marine technicians, and general tradespeople keep silicon bronze fasteners on hand for corrosive-environment connections.

This fastener fits residential and commercial applications where corrosion resistance is a priority. Typical uses include pump mounting, manifold assembly, fixture attachment in wet areas, and marine hardware connections. Silicon bronze is also compatible with copper alloy components, reducing galvanic corrosion concerns in plumbing and marine systems. The 25-piece pack quantity suits both single-job use and small-batch stocking.

Key Features

• Silicon bronze construction for strong corrosion resistance in wet and marine environments
• 1/4-20 UNC thread for broad compatibility with inch-series tapped holes
• 1-1/2-inch length under head suits medium-depth fastening applications
• 7/16-inch hex drive works with standard wrenches and sockets
• 25-piece pack quantity reduces per-unit cost for small-volume jobs

Compatibility

Designed for use in any application requiring a 1/4-20 UNC inch-series hex head cap screw, particularly where silicon bronze material is specified for corrosion resistance.

Installation Notes

Install with a 7/16-inch hex wrench, box wrench, or socket. Follow applicable mechanical codes for fastener material selection in wet or submerged environments. Do not mix silicon bronze fasteners with dissimilar metals in applications where galvanic corrosion is a concern. Inspect threads in the mating component before installation to ensure clean engagement.
