Value Collection 211293P Flat Socket Cap Screw 1/2-13 X 1-1/4 in

Product Description

The VALUE COLLECTION 211293P is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 1/2-13 UNC thread and an overall length of 1-1/4 inches. The 82-degree flat head seats fully into a matching countersunk hole, leaving a smooth surface when installed. Drive engagement is via a 5/16-inch hex socket. The alloy steel construction and black oxide finish provide strength and moderate corrosion resistance in general industrial and mechanical assembly environments. Licensed tradespeople and maintenance mechanics use this fastener in structural, machine, and fixture applications where a recessed head is required.

This screw is suited for use in machinery, tooling fixtures, brackets, and equipment enclosures where a countersunk profile is necessary to avoid interference with mating components or moving parts. Fully threaded along its entire 1-1/4-inch length, it provides consistent thread engagement in through-hole or thicker tapped applications. It is sold individually per package with a minimum order quantity of 100 units, making it appropriate for production runs or maintenance stocking programs where consistent fastener specs are critical across multiple installations.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 1/2-13 UNC thread for broad compatibility with inch-standard tapped holes
• 5/16-inch hex socket drive for high torque input without fastener damage
• Fully threaded for maximum thread engagement across the full length
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 standards
• Black oxide finish provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as a standard inch-series flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835, suitable for use in any application requiring a 1/2-13 UNC countersunk hex socket fastener.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance mechanics using a calibrated 5/16-inch hex key or socket driver. The mating hole must be countersunk to 82 degrees at the correct diameter to achieve proper flush seating. Ensure the tapped hole or nut meets the UNC 1/2-13 thread class specification before installation. De-energize and lock out any equipment before fastening components on powered machinery per applicable OSHA and facility lockout/tagout procedures.
