Value Collection -40867-2 Button Socket Cap Screw 50 Pack

Product Description

The VALUE COLLECTION -40867-2 is a button socket cap screw designed for precision fastening applications in mechanical assemblies, tooling, and fabrication work. It features a 10-32 UNF thread with a 3/4-inch length under the head and is driven by a 1/8-inch hex socket. Manufactured from alloy steel with a black oxide coating, this fastener delivers solid corrosion resistance and a clean, low-profile button head profile. Hardness is rated at 36-43 HRC, meeting the demands of load-bearing and torque-critical joints. This package contains 50 screws. Licensed machinists, millwrights, and field technicians are the typical installers.

This fastener is suited for use in industrial machinery, HVAC equipment panels, electrical enclosures, and fabricated metal assemblies where a smooth, rounded head profile is required. The button head style reduces snag points in moving assemblies. Fully threaded along the 3/4-inch shank, it provides full thread engagement across a range of material thicknesses. Compliance with ANSI/ASME B18.3 and ASTM F835 makes it appropriate for engineered assemblies requiring documented fastener standards.

Key Features

• 10-32 UNF thread, right-hand direction, Class 3A fit for precision engagement
• Button head style with 1/8-inch hex socket drive for low-profile installations
• Alloy steel construction hardened to 36-43 HRC
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Fully threaded shank along the 3/4-inch length under the head
• Meets ANSI/ASME B18.3 and ASTM F835 standards

Compatibility

Designed as a standard 10-32 UNF button socket cap screw for use in any assembly or fixture that accepts this thread size and head style per ANSI/ASME B18.3.

Installation Notes

Installation requires a 1/8-inch hex key or socket driver. Power down or de-energize any equipment before fastener service on electrical or HVAC panels. Apply appropriate torque using a calibrated tool per the assembly specification for 10-32 alloy steel fasteners. Do not substitute a mismatched driver size, as this will damage the socket recess.
