Holo-krome 61010 Flat Socket Cap Screw 10-32 X 1 in

Product Description

The HOLO-KROME 61010 is a flat socket cap screw designed for applications requiring a flush or countersunk head profile. Built from alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance in demanding mechanical and industrial assemblies. The 82-degree flat head seats cleanly into standard countersunk holes, eliminating protrusion above the mating surface. Drive engagement is through a 1/8 inch hex socket, providing positive torque transfer without head damage. At 10-32 x 1 inch fully threaded, it suits precision fastening tasks where thread engagement along the full length of the shank is required. Hardness is rated at 39-44 HRC, consistent with high-strength fastener requirements. Licensed trades and machine technicians working on equipment panels, fixtures, and assemblies are the primary installers.

This screw is used across a wide range of mechanical, industrial, and light structural applications where a low-profile or flush fastening solution is needed. Typical scenarios include equipment enclosures, machine guarding, fixture plates, and precision assemblies in manufacturing or maintenance environments. The UNF thread form and ASME B18.3 compliance make it a standard choice for inch-system designs where fine-thread engagement and dimensional consistency are required. The black oxide finish provides a clean appearance and mild surface protection suitable for indoor or protected environments. Professional trades including millwrights, maintenance technicians, and equipment assemblers routinely specify this fastener type.

Key Features

• 82-degree flat head seats flush in standard countersunk holes, eliminating surface protrusion
• 1/8 inch hex socket drive for positive torque engagement
• Fully threaded 10-32 UNF shank for maximum thread engagement along full length
• Alloy steel construction rated 39-44 HRC for high-strength fastening
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Meets ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style and replacement flat socket cap screw for inch-system mechanical assemblies requiring a 10-32 UNF fully threaded fastener with an 82-degree countersunk head profile per ASME B18.3.

Installation Notes

Installation should be performed by qualified mechanical trades or maintenance technicians using a calibrated 1/8 inch hex key or socket driver. De-energize and lock out all equipment before fastening into any assembly that contacts electrical or mechanical systems. Use the appropriate countersink angle and diameter for the mating surface to ensure full head seating without rocking. Do not exceed the torque capacity of the hex socket drive to avoid drive stripping or head damage.
