Value Collection R63061442 Flat Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R63061442 is a flat socket cap screw designed for fastening applications where a flush or countersunk finish is required. It features a 5/16-inch hex socket drive and an 82-degree flat head profile, allowing the fastener to sit flush with or below the mating surface. Manufactured from 18-8 stainless steel, it offers good corrosion resistance for use in wet, outdoor, or chemically exposed environments. The thread specification is 1/2-13 UNC with an overall length of 3/4 inches. This fastener is installed by machinists, maintenance technicians, millwrights, and general contractors working with inch-standard hardware.

This screw is suited for light to medium-duty structural and mechanical assemblies where a low-profile or countersunk fastener is needed. The 1/2-13 UNC thread is a coarse-thread standard, making it compatible with a wide range of tapped holes and threaded inserts used in general fabrication, equipment mounting, and panel attachment. The 18-8 stainless steel construction makes it a common choice for food processing, marine-adjacent, and outdoor equipment applications where mild corrosion resistance is a priority.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 5/16-inch hex socket drive for internal wrench engagement
• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Overall length of 3/4 inches suits shallow-clearance fastening applications

Compatibility

Designed for use in standard 1/2-13 UNC tapped holes requiring an 82-degree countersunk flat head fastener per inch-standard fastener specifications.

Installation Notes

Install using a 5/16-inch hex key or Allen driver; avoid using impact tools on stainless steel fasteners to reduce the risk of galling on the threads. Verify the mating hole is chamfered to an 82-degree angle before seating the fastener flush. Apply an anti-seize compound to the threads when installing stainless steel fasteners into stainless steel tapped holes to prevent galling and seizure. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the assembly.
