Value Collection -40866-2 Button Cap Screw 10-32 1/2in 50pk

Product Description

The VALUE COLLECTION -40866-2 is a 10-32 button socket cap screw designed for fully threaded fastening applications in mechanical assemblies, fixtures, and equipment. The button head profile provides a low-clearance seating surface, while the 1/8-inch hex socket drive allows precise torque application in tight spaces. Constructed from alloy steel with a black oxide finish, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. Hardness is rated at 36-43 HRC, and the thread fit is Class 3A with right-hand thread direction. Each package contains 50 screws.

This fastener is suited for use in general industrial, mechanical, and maintenance applications where a low-profile head is required. The 10-32 UNF thread pattern is commonly used in instrument panels, machine frames, electrical enclosures, and precision assemblies. The black oxide finish provides mild corrosion resistance and reduces light reflection in applications where appearance or glare is a factor. Installation requires a 1/8-inch hex key or Allen driver.
