Value Collection 019157PR Low Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 019157PR is a low socket cap screw designed for applications where a standard-height cap screw head would interfere with mating components or clearance constraints. Threaded 1/4-20 UNC and measuring 1-1/4 inches in length under the head, this fastener is fully threaded and driven with a 1/8-inch hex key. The body is machined from alloy steel and finished in black oxide, which provides moderate corrosion resistance and reduces light reflection in finished assemblies. Torquing is performed with a standard hex socket or L-key. This screw conforms to ASME/ANSI B18.8 dimensional standards and is suited for use by machinists, millwrights, maintenance technicians, and general industrial assembly personnel.

Low socket cap screws of this profile are commonly used in machine tool fixtures, jigs, tooling plates, and mechanical assemblies where a low-profile head is required to maintain clearance over moving parts or adjacent surfaces. The 1/4-20 UNC thread is one of the most widely specified coarse-thread sizes in inch-system fastener applications, making this screw a standard fit in a broad range of industrial and light-duty mechanical assemblies. Alloy steel construction supports higher strength applications compared to plain carbon or stainless alternatives. This item is sold individually but carries a minimum order quantity of 100 pieces.

Key Features

• Low socket cap head profile reduces interference in tight-clearance assemblies
• Fully threaded 1/4-20 UNC, length 1-1/4 inches measured under head
• 1/8-inch hex socket drive for standard L-key or hex bit installation
• Alloy steel construction for elevated tensile strength versus plain carbon steel
• Black oxide finish for moderate corrosion resistance and reduced surface reflectivity
• Conforms to ASME/ANSI B18.8 fastener standard

Compatibility

Designed as a standard inch-system low socket cap screw for use in any application calling for a 1/4-20 UNC fully threaded fastener with a low-profile hex socket head per ASME/ANSI B18.8.

Installation Notes

Installation is performed with a 1/8-inch hex key or equivalent hex socket bit. Power down or de-energize any equipment before servicing fastened assemblies. Do not exceed the torque capacity appropriate for alloy steel fasteners at this thread size; consult applicable engineering references for torque specifications. Inspect threads in the mating part for cleanliness and proper thread engagement before final torquing.
