Value Collection 721134PR Flat Socket Cap Screw 10-32x2

Product Description

The VALUE COLLECTION 721134PR is a flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies. It features an 82-degree flat head profile with a 1/8 inch hex socket drive, allowing installation with a standard hex key. The fastener is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection in finished assemblies. At 2 inches in overall length with partial threading, it is suited for through-hole and blind-hole applications where a grip section is needed. Licensed machinists, millwrights, and general mechanical contractors commonly use this screw in precision fabrication and equipment assembly work.

This screw is appropriate for inch-series threaded assemblies requiring a low-profile flush-mount head. The 10-32 UNF thread standard is common in light machinery, instrumentation panels, electronics enclosures, and general industrial fabrication. Partial threading leaves an unthreaded shank near the head, which helps align mating components and provides a clamping grip section. The black oxide finish is suitable for indoor or protected environments where moderate corrosion resistance is acceptable.

Key Features

• 82-degree flat head seats flush in standard countersunk holes per ASME/ANSI B18.3 and ASTM F835
• 1/8 inch hex socket drive for precise torque application with a standard hex key or Allen driver
• 10-32 UNF thread for fine-pitch, high-strength engagement in inch-series assemblies
• Alloy steel construction for higher tensile and shear strength compared to standard steel fasteners
• Black oxide finish reduces surface reflectivity and provides light corrosion protection
• Partial threading provides an unthreaded grip section for alignment and clamping

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 10-32 UNF countersunk fastener per ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Install using a calibrated 1/8 inch hex key or T-handle driver. Ensure the mating countersink is machined to an 82-degree included angle to achieve proper head seating and avoid stress concentration. De-energize or lock out any equipment before fastener replacement or removal per applicable OSHA lockout/tagout procedures. Avoid over-torquing, as alloy steel screws in fine-thread applications are susceptible to thread stripping if torque limits are exceeded.
