Holo-krome 61004 Flat Socket Cap Screw 10-32 X 0.5 in

Product Description

The HOLO-KROME 61004 is a flat socket cap screw designed for applications where a flush or countersunk fastener profile is required. It features an 82-degree flat head driven by a 1/8-inch hex socket. The screw measures 10-32 (UNF) thread size at 0.5 inches overall length and is fully threaded from tip to head. Constructed from alloy steel with a black oxide finish, it meets ASME B18.3 and ASTM F835 standards. Hardness is rated at 39 to 44 HRC, making it suitable for demanding mechanical and structural assembly work. Licensed technicians and millwrights working in tight clearance or precision equipment environments are the primary installers.

This screw is used in mechanical assemblies, machine guarding, tooling fixtures, enclosures, and precision equipment where a flush-mounted fastener is required. The black oxide finish provides mild corrosion resistance and reduces light reflection, which is useful in optical, electronic, or industrial equipment installations. It is sold in minimum order quantities of 100 pieces, making it appropriate for production or maintenance shop stocking.

Key Features

• 82-degree flat head for flush or countersunk installation in standard countersunk holes
• 1/8-inch hex socket drive compatible with standard hex key sets
• Fully threaded 10-32 UNF thread for consistent grip along the entire shank
• Alloy steel construction rated 39 to 44 HRC for high-strength fastening
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Meets ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 10-32 UNF fully threaded flat socket cap screw with an 82-degree countersunk head profile per ASME B18.3.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or technician familiar with threaded fastener procedures. Ensure the mating material is tapped to a 10-32 UNF thread class 3A specification before installation. De-energize and lock out all equipment before servicing any assembly that includes these fasteners. Do not exceed the torque range appropriate for 10-32 alloy steel fasteners in the mating material type, and consult applicable engineering references for torque values.
