Value Collection 36819 Flat Socket Cap Screw 1/4-20 X 3 in

Product Description

The VALUE COLLECTION 36819 is a flat socket cap screw designed for flush or countersunk fastening applications in metal, wood, and composite assemblies. The 82-degree flat head seats flush with the material surface, and the 5/32-inch hex socket drive accepts a standard hex key for installation and removal. At 3 inches in overall length with a 1/4-20 UNC thread, this fastener is partially threaded, placing the smooth shank section near the head to allow for controlled clamping in close-tolerance assemblies. The alloy steel construction with black oxide finish provides corrosion resistance in moderately humid environments. Licensed mechanics, machinists, and maintenance technicians install this type of fastener across a wide range of industrial and equipment service applications.

This screw is suited for use in mechanical assemblies, equipment enclosures, jigs, fixtures, and structural joins where a low-profile flush head is required. The 1/4-20 UNC thread pattern is one of the most common inch-series fastener sizes in North American trade applications, making this screw a standard replacement or repair fastener for machinery, brackets, and fabricated assemblies. It ships in packages of 25, making it practical for maintenance stock or small-batch production builds.

Key Features

• 82-degree flat head seats flush with countersunk material surfaces
• 5/32-inch hex socket drive for precise torque application with a standard hex key
• 1/4-20 UNC thread standard, compatible with the most common inch-series tapped holes
• Partial threading allows smooth shank engagement for close-tolerance clamping
• Alloy steel construction with black oxide finish for added surface durability
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard OEM-style replacement or service fastener for any assembly requiring a 1/4-20 UNC flat socket cap screw with an 82-degree countersunk head profile.

Installation Notes

Install using a 5/32-inch hex key or Allen driver; ensure the mating hole is properly countersunk to 82 degrees before seating the fastener. Power down or de-energize any equipment before accessing fastener points on live machinery. Follow applicable torque specifications for 1/4-20 alloy steel fasteners as defined by the equipment manufacturer or relevant ASME guidelines. Avoid over-torquing, which can strip the socket drive or damage the countersunk seat.
