The HOLO-KROME 720000550 is a hex socket cap screw designed for applications requiring a secure, high-strength threaded fastener in tight or recessed spaces. This screw features an 8-32 UNC thread and is fully threaded along its 7/16-inch length under the head. The drive is a 9/64-inch internal hex socket, driven with a standard hex key or Allen wrench. Constructed from alloy steel with a black oxide coating, it delivers solid mechanical strength along with a degree of corrosion resistance in dry indoor environments. It conforms to ASME B18.3 and ASTM A574 standards, making it suitable for demanding mechanical assemblies.
This screw is used across a wide range of mechanical, industrial, and equipment assembly applications. The 8-32 UNC thread is a common size in light machinery, HVAC equipment panels, electrical enclosures, and similar assemblies where a compact, recessed-drive fastener is needed. The black oxide alloy steel construction suits indoor and controlled-environment installations. This item is sold in a minimum order quantity of 100 pieces per order, making it appropriate for shop stock, service vans, or production line use.
Designed as a standard 8-32 UNC hex socket cap screw conforming to ASME B18.3, suitable for use in any application requiring that thread size and drive type with alloy steel construction.
Install using a 9/64-inch hex key or Allen wrench; do not use an oversized or worn key, as this can strip the socket drive. Ensure the mating threaded hole is clean and free of debris before driving the screw. Follow applicable torque guidelines from the equipment manufacturer or applicable ASME standards for 8-32 alloy steel fasteners. Inspect for proper thread engagement before applying final load.
