Value Collection 88547914 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 88547914 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. The flat head sits flush with or below the surface of the mated material, making it suitable for assemblies where a protruding head would interfere with fit or function. Driven by a 5/32-inch hex socket, this screw is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection. The 1/4-20 UNC thread pattern and 1-1/4-inch overall length make it a common choice in mechanical assemblies, fixturing, and equipment fabrication.

This flat socket cap screw is used across a wide range of industrial, mechanical, and fabrication applications. It is well suited for mounting panels, brackets, and components where a low-profile head is required. The partially threaded shank allows for clamping force between two surfaces without the threads engaging both members, which is a common requirement in precision assemblies. Machinists, millwrights, and maintenance technicians working with steel or aluminum assemblies will recognize this as a standard inch-series fastener.

Key Features

• Flat head profile allows flush or countersunk installation in mating surfaces
• 5/32-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 1/4-20 UNC thread standard, compatible with common tapped holes and nuts in inch-series assemblies
• Partially threaded shank for proper clamping in two-member joints
• Alloy steel construction provides high tensile strength for demanding mechanical applications
• Black oxide finish reduces surface reflectivity and offers light corrosion resistance in dry environments

Compatibility

Designed as a standard inch-series flat socket cap screw suitable for 1/4-20 UNC tapped holes in metal, plastic, and composite assemblies requiring a countersunk or flush fastener profile.

Installation Notes

Installation requires a 5/32-inch hex key or Allen driver; use of a torque wrench with the appropriate hex bit is recommended for controlled assembly. Countersink the mating hole to the correct included angle for flat head screws before installation. Power down any equipment and relieve all system pressure before replacing fasteners in active assemblies. Follow applicable mechanical codes and the equipment manufacturer's assembly specifications for fastener torque requirements.
