Value Collection 33431 Low Socket Cap Screw 1/2-13 Alloy Steel

Product Description

The VALUE COLLECTION 33431 is a low socket cap screw designed for applications where standard socket cap head height is not acceptable. Sized at 1/2-13 thread and 1-1/4 inches in length under head, this fastener is fully threaded and driven with a 1/4-inch hex key. It is manufactured from alloy steel and finished with black oxide, which provides moderate corrosion resistance and reduces light reflection. Machinists, millwrights, and mechanical contractors use this style of fastener where vertical clearance is limited but high clamping strength is required.

This low socket cap screw is suited for machine assemblies, tooling fixtures, and mechanical equipment where a recessed drive is preferred over an external hex or Phillips head. The fully threaded shank and UNC thread form make it compatible with standard 1/2-13 tapped holes in steel, aluminum, and other metals. It is packaged in a quantity of 25 per package, making it practical for shop stock, maintenance kits, or production line use.

Key Features

• Low socket cap head profile for use in tight vertical clearance installations
• Fully threaded shank provides full thread engagement along the entire fastener length
• 1/4-inch hex socket drive for standard hex key or T-handle tools
• Alloy steel construction offers high tensile strength for mechanical fastening applications
• Black oxide finish provides mild corrosion resistance and a non-reflective surface
• Meets ASME/ANSI B18.8 fastener standard

Compatibility

Designed as an OEM-style replacement or shop-stock fastener for any assembly requiring a 1/2-13 UNC fully threaded low socket cap screw in a standard tapped hole per ASME/ANSI B18.8.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical technicians using a 1/4-inch hex key or socket driver. Ensure the mating tapped hole meets 1/2-13 UNC thread specifications before installation. De-energize and lock out any equipment before fastener replacement or assembly work. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
