Holo-krome 78042 Hex Socket Cap Screw 10-24 Unc Stainless

Product Description

The HOLO-KROME 78042 is a hex socket cap screw designed for applications requiring a clean, recessed-drive fastener with reliable holding strength. Threaded 10-24 UNC and fully threaded along its 3/4 inch length under head, this screw accepts a 5/32 inch hex key drive. The body is machined from 18-8 stainless steel with a bright, uncoated finish, giving it solid corrosion resistance in general industrial, mechanical, and light structural assemblies. It meets ASME B18.3 and ASTM F837 standards, which makes it a traceable, spec-grade fastener. Maintenance technicians, mechanical assemblers, and field service professionals across HVAC, plumbing, and electrical trades use socket cap screws like this wherever a flush or countersunk fastener head is required in tight quarters.

This screw is suited for use in light-duty mechanical assemblies, equipment panels, junction boxes, brackets, and component mounting applications where a standard hex head would interfere with adjacent hardware or enclosures. Its 10-24 UNC thread is one of the most common inch-series machine screw threads, making it a practical stock item for service vans and shop inventory. The fully threaded shank provides maximum thread engagement across the entire 3/4 inch length, which is useful when threading into thin stock or shallow tapped holes. Sold individually per the package quantity of 1 unit; minimum order quantity is 100 pieces.

Key Features

• 10-24 UNC thread for broad compatibility with standard inch-series tapped holes
• Fully threaded 3/4 inch length under head for maximum thread engagement
• 5/32 inch hex socket drive allows use in recessed or low-clearance locations
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Meets ASME B18.3 and ASTM F837 dimensional and material standards
• Bright uncoated finish - no risk of coating flaking in clean or sensitive assemblies

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 10-24 UNC hex socket cap screw with a 3/4 inch length under head and 5/32 inch drive.

Installation Notes

Install using a calibrated 5/32 inch hex key or Allen driver; use of an incorrectly sized driver can strip the socket recess. Ensure tapped holes are clean and free of debris before driving. Apply appropriate thread lubricant or anti-seize if installing into dissimilar metals to prevent galling, which is a common issue with stainless fasteners. Follow applicable torque guidelines from ASME or the equipment manufacturer for 10-24 UNC fasteners in the given material.
