Value Collection C32424844 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION C32424844 is a 5/16-18 UNC flat socket cap screw manufactured from 316 stainless steel. It features an 82-degree flat head profile with a 3/16-inch hex socket drive. The overall length is 3-1/2 inches. This fastener is used in mechanical assemblies, structural connections, and equipment fabrication where a flush-mounted, corrosion-resistant fastener is required. Installation is performed by machinists, millwrights, maintenance technicians, and fabricators working with stainless hardware in corrosive or marine-adjacent environments.

This flat socket cap screw is suited for applications requiring a countersunk, flush-seating head in metal or composite substrates. The 316 stainless steel alloy provides superior resistance to chlorides and oxidizing agents compared to 304-grade material, making it appropriate for marine, food-processing, chemical, and outdoor industrial installations. The UNC thread standard ensures broad compatibility with standard inch-system tapped holes and nuts.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a clean, low-profile installation
• 3/16-inch hex socket drive accepts standard Allen keys and hex bit drivers
• 316 stainless steel construction resists corrosion in chloride-heavy and outdoor environments
• 5/16-18 UNC thread provides strong clamping force in inch-standard tapped holes
• 3-1/2-inch overall length accommodates deeper material stacks requiring extended engagement
• Minimum order quantity of 5 units supports small-batch repair and fabrication needs

Compatibility

Designed as an inch-standard UNC fastener for use in any application requiring a 5/16-18 flat socket cap screw with an 82-degree countersink angle.

Installation Notes

Install using a calibrated 3/16-inch hex key or hex bit driver to ensure proper torque transfer without rounding the socket. Countersink the mating hole to an 82-degree included angle for full head seating. Apply an appropriate anti-seize compound when installing 316 stainless fasteners into stainless threaded holes to prevent galling. Inspect threads and seating surface before installation to confirm no damage that could affect clamping performance.
