Holo-krome 60032 Flat Socket Cap Screw 8-32 3/8 in Alloy Steel

Product Description

The HOLO-KROME 60032 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Built from alloy steel with a black oxide finish, it delivers strong corrosion resistance and a low-reflectance surface suited for mechanical assemblies, tooling fixtures, and equipment enclosures. The 82-degree flat head seats cleanly into standard countersunk holes, and the hex socket drive accepts a 3/32-inch hex key for precise torque application in tight spaces. Hardness is rated at 39-44 HRC, meeting the mechanical requirements of demanding industrial and trade installations.

This screw is a standard inch-series fastener sized at 8-32 thread by 3/8-inch overall length. It is fully threaded, making it suitable for through-hole and shallow-boss applications across HVAC equipment panels, electrical enclosures, plumbing equipment housings, and general mechanical assemblies. The black oxide finish is common in applications where a non-reflective, corrosion-inhibiting surface is preferred over a bright finish. This fastener is appropriate for use by machinists, millwrights, HVAC technicians, and maintenance professionals working on light to medium-duty equipment.

Key Features

• 82-degree flat head for flush countersunk installation
• 3/32-inch hex socket drive for use with standard hex keys
• Alloy steel construction rated 39-44 HRC for high tensile strength
• Black oxide finish provides corrosion inhibition and low reflectance
• Fully threaded along the 3/8-inch overall length
• Meets ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series flat socket cap screw compatible with any 8-32 UNC countersunk through-hole or tapped application conforming to ASME B18.3 dimensional standards.

Installation Notes

Install using a calibrated 3/32-inch hex key or hex bit driver. Ensure the mating countersink is machined to 82 degrees to achieve proper head seating and flush finish. Disconnect power or shut off relevant systems before fastening components inside electrical enclosures or HVAC equipment panels. Avoid over-torquing, which can strip the socket drive or damage the threaded bore in softer base materials.
