Value Collection 90440 Hex Head Cap Screw 3/8-16 X 1/2 in Brass

Product Description

The VALUE COLLECTION 90440 is a 3/8-16 hex head cap screw machined from brass, sized at 1/2 inch under the head with a 9/16-inch hex drive. Brass construction provides natural corrosion resistance and non-magnetic properties, making this fastener a reliable choice for electrical enclosures, plumbing fittings, marine hardware, and other applications where ferrous fasteners are unsuitable. The 3/8-16 thread designation follows the Unified National Coarse (UNC) standard, ensuring broad compatibility with tapped holes and standard brass or stainless nuts. Plumbers, electricians, and mechanical contractors regularly specify brass cap screws where dissimilar-metal corrosion or conductivity is a concern.

This screw is suited for light-duty mechanical assemblies, panel mounting, fixture attachment, and equipment enclosure work in residential and commercial settings. The UNC thread form seats reliably in standard tapped holes without requiring metric tooling or specialty adapters. Sold in a pack of 50, this fastener is a practical bench stock item for service vans, shop inventory, or job-site hardware kits where brass fasteners are regularly consumed.

Key Features

• Brass construction resists corrosion and eliminates magnetic interference concerns
• 3/8-16 UNC thread for broad compatibility with standard tapped holes and nuts
• 1/2-inch length under head suits shallow-clearance assemblies and thin panels
• 9/16-inch hex drive works with standard open-end, box-end, and socket wrenches
• Pack of 50 supports bench stock and field service inventory needs

Compatibility

Designed as a standard UNC hex head cap screw for use in any application requiring a 3/8-16 thread pitch in brass material.

Installation Notes

Install using a 9/16-inch wrench or socket. Brass is a softer alloy than steel — avoid impact drivers and do not overtighten, as the threads and head are susceptible to stripping or deformation under excessive torque. Ensure the mating tapped hole is clean and free of debris before driving the screw. Follow applicable NEC or IPC guidelines when these fasteners are used in electrical or plumbing assemblies.
