Holo-krome 64008 Button Socket Cap Screw 6-32 1/4in

Product Description

The HOLO-KROME 64008 is a button socket cap screw designed for applications requiring a low-profile head and reliable clamping strength. It features a 6-32 UNC thread and a 1/4-inch length under head, fully threaded, making it well suited for securing components where head clearance is limited. Driven by a 5/64-inch hex socket, the screw is machined from alloy steel with a black oxide finish that provides moderate corrosion resistance. Hardness is rated at 38 HRC, and the thread fit is Class 3A for consistent, close-tolerance engagement. Licensed contractors, maintenance technicians, and assembly professionals install this fastener across a range of mechanical and structural applications.

This screw is commonly used in light mechanical assemblies, electrical enclosure work, panel mounting, and equipment fabrication where a low-profile button head is preferred over a standard socket head. The black oxide finish suits indoor and light-duty applications. The fully threaded 6-32 shank works with standard tapped holes or threaded inserts meeting ANSI/ASME B18.3 and ASTM F835 standards. This fastener is sold in multiples of 100 and is packaged individually per unit as specified.

Key Features

• Button head profile reduces snag points and suits flush or near-flush installations
• 6-32 UNC thread, fully threaded, Class 3A fit for close-tolerance engagement
• 5/64-inch hex socket drive for standard Allen key or hex bit driver
• Alloy steel construction rated at 38 HRC hardness
• Black oxide finish for light corrosion resistance in dry or indoor environments
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard fastener for use in any application requiring a 6-32 UNC button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835 specifications.

Installation Notes

Installation is performed with a 5/64-inch hex key or matching hex bit driver. Ensure the mating tapped hole meets 6-32 UNC Class 3A or 3B thread specifications before installation. Do not overtighten; alloy steel button head screws have a lower torque threshold than standard socket head cap screws due to the smaller head geometry. Confirm thread engagement is sufficient before applying torque to avoid stripping.
