Value Collection -40867-1 Button Socket Cap Screw 10-24

Product Description

The VALUE COLLECTION -40867-1 is a 10-24 fully threaded button socket cap screw designed for fastening applications that require a low-profile head and reliable clamping strength. Manufactured from alloy steel with a black oxide finish, this screw offers corrosion resistance and a hardness rating of 36-43 HRC. The hex socket drive accepts a 1/8 inch hex key for installation in confined spaces where standard wrench clearance is limited. It conforms to ANSI/ASME B18.3 and ASTM F835 standards, making it a direct fit for precision mechanical assemblies, machine components, and structural fabrication work.

This fastener is suited for use in industrial, mechanical, and light structural applications where a flush or near-flush head profile is preferred over a traditional hex cap screw. The UNC thread form and Class 3A thread fit provide tight tolerances and consistent engagement. Machinists, fabricators, millwrights, and maintenance technicians commonly use this style of fastener in equipment enclosures, panel mounting, fixture assembly, and general machine building. The black oxide finish makes it a common choice in applications where surface reflectivity needs to be minimized.

Key Features

• 10-24 UNC fully threaded with Class 3A thread fit for precise engagement
• Button head profile provides a low-profile seating surface
• 1/8 inch hex socket drive for installation in tight clearance areas
• Alloy steel construction with 36-43 HRC hardness rating
• Black oxide finish for mild corrosion resistance and low reflectivity
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 10-24 UNC button socket cap screw suitable for use in mechanical assemblies, machine components, and fabrication applications requiring a low-profile hex socket fastener conforming to ANSI/ASME B18.3.

Installation Notes

Installation requires a 1/8 inch hex key or ball-end hex driver. Ensure mating threads are clean and free of debris before driving the fastener. Do not exceed the rated torque range for 10-24 alloy steel fasteners as specified by the applicable ANSI/ASME standard. Right-hand thread direction — turn clockwise to tighten.
