Value Collection 88547922 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 88547922 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a hex socket drive and is manufactured from alloy steel with a black oxide finish for corrosion resistance in moderate environments. The screw is 1/4-20 thread size, 1-1/2 inches in overall length, and is partially threaded along its shank. Machinists, millwrights, and maintenance technicians commonly install this fastener in metal-to-metal assemblies where a low-profile head is required to avoid interference with mating parts or covers.

This flat socket cap screw is suited for use in mechanical assemblies, fixtures, machine guards, and structural fabrication where the head must sit flush with or below the surface of the work material. The UNC thread standard and inch-system sizing make it compatible with standard tapped holes in imperial dimensions. It ships in a package quantity of 13 units, with a minimum order quantity of 1.

Key Features

• Flat head profile allows flush or countersunk installation to eliminate head protrusion
• Hex socket drive accepts a 5/32 inch hex key for reliable torque application in confined spaces
• Alloy steel construction provides high tensile strength for demanding mechanical applications
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Partial threading preserves shank grip strength and allows clamping force across unthreaded sections
• UNC thread standard ensures compatibility with standard inch-system tapped holes

Compatibility

Designed as a standard inch-system UNC flat socket cap screw for use in any tapped or clearance-hole assembly specifying a 1/4-20 thread, 1-1/2 inch overall length, and a countersunk flat head profile.

Installation Notes

Installation requires a 5/32 inch hex key or Allen driver. Countersink the mating hole to the appropriate angle to achieve a flush seating surface before driving the screw. De-energize or lock out any machinery before fastener service in powered equipment. Follow applicable industry torque guidelines for 1/4-20 alloy steel fasteners as specified by the equipment manufacturer or relevant standards.
