Holo-krome 60034 Flat Socket Cap Screw 8-32 X 0.5 in

Product Description

The HOLO-KROME 60034 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head with a 3/32-inch hex socket drive, allowing installation with a standard hex key. The screw is manufactured from alloy steel with a black oxide finish, providing moderate corrosion resistance and a low-reflectance appearance. It carries a Thread Fit Class 3A designation and meets ASME B18.3 and ASTM F835 standards. Hardness is rated at 39 to 44 HRC, making it suitable for moderate to high-load fastening tasks. Machinists, tool-and-die technicians, and maintenance mechanics are the primary installers.

This screw is used in machine assemblies, fixtures, tooling plates, and enclosures where a protruding head is not acceptable. The 8-32 UNC thread and 0.5-inch overall length fit a wide range of light-duty to medium-duty mechanical assemblies. The black oxide finish makes it a common choice in applications where surface glare or bare metal exposure needs to be minimized. It is fully threaded along its entire 0.5-inch length, ensuring maximum thread engagement in thin materials.

Key Features

• 82-degree flat head sits flush or below the mating surface when countersunk correctly
• 3/32-inch hex socket drive for precise torque application with a standard Allen key
• Alloy steel construction rated at 39 to 44 HRC for high shear and tensile strength
• Black oxide finish reduces reflectance and provides light surface protection
• Fully threaded 0.5-inch body maximizes engagement in shallow through-holes
• Meets ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 8-32 UNC flat socket cap screw for use in countersunk holes machined to accept an 82-degree flat-head fastener per ASME B18.3 specifications.

Installation Notes

Installation requires a countersunk hole machined to an 82-degree included angle to achieve a proper flush seating. Use the correct 3/32-inch hex key to avoid rounding the socket drive. De-energize or lock out any equipment before replacing or installing fasteners in live machinery. Follow applicable ASME or facility torque guidelines for 8-32 alloy steel fasteners.
