Value Collection 019145PR Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 019145PR is a low socket cap hex socket drive screw designed for applications where a standard-height cap head would interfere with mating components or clearance is limited. Sized at 1/4-20 UNC x 1/2 inches and fully threaded from head to tip, this fastener is driven with a 1/8-inch hex key. Manufactured from alloy steel with a black oxide finish, it provides moderate corrosion resistance and reduces light glare in assemblies. The ASME/ANSI B18.8 standard governs its dimensional and mechanical tolerances. Installers working in tight counterbore pockets or low-profile mounting applications will find this screw well suited to the task.

This fastener is appropriate for light-to-medium duty mechanical assemblies in industrial, HVAC, electrical enclosure, and general fabrication settings. The low socket cap head profile makes it a common choice when standard socket cap heads exceed available headroom, such as in panel mounts, fixtures, jigs, and equipment housings. The black oxide finish is typical in applications where a dark, low-reflectance appearance is preferred or where parts are lightly oiled after installation for added protection.

Key Features

• Low socket cap head profile for use in tight-clearance or counterbore applications
• 1/4-20 UNC fully threaded — compatible with standard 1/4-20 tapped holes
• 1/8-inch hex key drive (0.125 inches nominal)
• Alloy steel construction for strength in mechanical assemblies
• Black oxide finish for low-reflectance appearance and mild corrosion resistance
• Conforms to ASME/ANSI B18.8 dimensional standard

Compatibility

Designed for use in any application requiring a 1/4-20 UNC tapped hole with a low-profile socket cap head fastener; compatible with standard 1/4-20 threaded inserts, nuts, and tapped aluminum, steel, or plastic components.

Installation Notes

Install using a 1/8-inch hex key or Allen-type driver; avoid cam-out by seating the key fully before applying torque. Ensure the mating tapped hole meets ASME/ANSI B18.8 thread specifications to maintain proper engagement. Black oxide finish provides minimal corrosion protection on its own — apply a light oil or wax coating after assembly in humid or outdoor environments. Always de-energize and lock out equipment before replacing fasteners on energized enclosures or mechanical systems.
