Value Collection 201057P Button Socket Cap Screw 10-24

Product Description

The VALUE COLLECTION 201057P is a button socket cap screw designed for applications requiring a low-profile head and high clamping strength. Sized at 10-24 x 1/2 inch with a fully threaded shank, this fastener is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and a clean, uniform appearance. The 1/8-inch hex socket drive accepts a standard hex key for installation in confined spaces where a wrench cannot reach. Hardness is rated at 36 to 43 HRC, meeting the mechanical requirements of ANSI/ASME B18.3 and ASTM F835. Machinists, millwrights, and assembly technicians regularly install this type of fastener in machinery, fixtures, and equipment enclosures.

This button socket cap screw is suited for light to medium clamping loads in mechanical assemblies where a flat, rounded head profile is preferred over a standard hex cap or socket head. The UNC thread form and 3A thread fit class ensure consistent engagement with standard tapped holes in steel, aluminum, and similar materials. Typical applications include machine guarding, panel mounting, fixture plates, and precision equipment assemblies in industrial and manufacturing environments.

Key Features

• Low-profile button head reduces snagging hazard in moving assemblies
• Alloy steel construction with 36 to 43 HRC hardness rating
• Black oxide finish for mild corrosion resistance and reduced glare
• 1/8-inch hex socket drive for use in restricted-access locations
• Fully threaded shank with UNC thread form and 3A fit class
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard 10-24 UNC tapped holes in steel, aluminum, and similar materials as an OEM-style or replacement button socket cap screw in industrial and mechanical assemblies.

Installation Notes

Installation is performed with a 1/8-inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply fastener to the correct torque specification for the joint material and application per applicable engineering or equipment requirements. Do not exceed the rated hardness limits by substituting this fastener into joints requiring grade-specific load ratings without verifying compatibility.
