Value Collection C32424334 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION C32424334 is a 5/16-18 UNC flat socket cap screw machined from 316 stainless steel. It measures 2 inches in overall length and features an 82-degree flat head profile with a 3/16-inch hex socket drive. The 316 alloy provides strong resistance to corrosion in wet, chemical, and marine environments, making this fastener well suited for plumbing, HVAC, pool equipment, and other trade applications where stainless hardware is specified. Licensed tradespeople and maintenance technicians install this type of fastener where a flush or countersunk installation is required and standard hex cap screws would protrude above the surface.

This flat socket cap screw is used in residential and commercial mechanical installations that call for a countersunk fastener with a high-torque internal drive. Common applications include mounting brackets, access panels, pump housings, and equipment frames where a flush finish is required. The UNC thread form is standard for inch-system assemblies. The 316 stainless grade is preferred in coastal, poolside, and chemical-service environments over standard 304 stainless.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 3/16-inch hex socket drive accepts standard Allen or hex-key tools
• 316 stainless steel resists corrosion in wet, salt, and chemical-exposure environments
• 5/16-18 UNC thread for compatibility with standard inch-system tapped holes
• 2-inch overall length suits medium-depth fastening applications

Compatibility

Designed as a standard inch-system flat socket cap screw for use in any application requiring a 5/16-18 UNC countersunk fastener in 316 stainless steel.

Installation Notes

Install using a 3/16-inch hex key or Allen driver; ensure the mating hole is properly countersunk to 82 degrees for full head seating. Shut down and de-energize or depressurize any system before removing or replacing fasteners on live mechanical assemblies. Do not overtighten in softer base materials; apply appropriate thread engagement based on the base material specification. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque in structural or pressure-boundary applications.
