Value Collection MP63858 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION MP63858 is a flat socket cap screw designed for applications where a flush or countersunk fastener profile is required. Featuring a 1/4-20 UNC thread and an overall length of 3/4 inches, this screw is manufactured from 18-8 stainless steel for reliable corrosion resistance in a wide range of service environments. The 82-degree flat head seats cleanly into standard countersunk holes, and the 5/32-inch hex socket drive allows precise torque application with a standard hex key or Allen driver. Machinists, millwrights, fabricators, and maintenance technicians working on assemblies that require a low-profile fastener will find this screw well suited to the task.

This screw is appropriate for light-duty mechanical assemblies, panels, enclosures, brackets, and equipment frames where a flush fastener surface is necessary. The 18-8 stainless steel construction makes it suitable for indoor and mildly corrosive outdoor environments, including food-service equipment, marine hardware, and general industrial applications. The 1/4-20 UNC thread is one of the most common inch-series thread standards in North American trade work, making this fastener broadly compatible with standard tapped holes and threaded inserts of the same specification.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a low-profile finish
• 1/4-20 UNC thread provides broad compatibility with standard North American tapped holes and inserts
• 18-8 stainless steel construction resists corrosion in mildly corrosive and moisture-exposed environments
• 5/32-inch hex socket drive accepts standard Allen keys and hex bit drivers
• 3/4-inch overall length suits shallow to medium-depth fastening applications

Compatibility

Designed as a standard inch-series flat socket cap screw compatible with any 1/4-20 UNC tapped hole or threaded insert requiring an 82-degree countersunk seating surface.

Installation Notes

Installation is performed with a 5/32-inch hex key or Allen-style bit driver. Ensure the mating countersink is machined to an 82-degree included angle for proper head seating. Avoid over-torquing in soft base materials, as the stainless steel fastener can gall or strip the receiving thread. De-energize or lock out any equipment before replacing fasteners on live assemblies.
