Value Collection MSC-67611442 Hex Socket Cap Screw 4-40 Unc

Product Description

The VALUE COLLECTION MSC-67611442 is a hex socket cap screw designed for precision fastening in mechanical assemblies, fixtures, and equipment requiring a low-profile, high-strength threaded fastener. It features a 4-40 UNC thread size with a 7/16 inch length under head and is fully threaded from bearing surface to tip. The 3/32 inch hex socket drive accepts a standard hex key or Allen driver. Constructed from 18-8 stainless steel with a bright uncoated finish, this screw provides corrosion resistance suitable for general industrial, marine-adjacent, and laboratory applications. It is installed by machinists, maintenance technicians, and fabricators working with light-gauge components.

This screw is suited for applications where a flush or recessed drive head is required and torque must be applied with a hex key. The 4-40 UNC thread is a fine-pitch imperial thread commonly found in instrument panels, electronic enclosures, small mechanical assemblies, and precision fabrication. The 18-8 stainless steel construction makes it appropriate for environments where mild corrosion resistance is needed without the cost of a coated carbon steel fastener. This item is sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• 4-40 UNC thread standard for compatibility with imperial-threaded instrument and enclosure hardware
• Fully threaded along the 7/16 inch length under head for maximum thread engagement in thin stock
• 3/32 inch hex socket drive accepts standard hex keys and hex bit drivers
• 18-8 stainless steel construction provides corrosion resistance without a surface coating
• Bright uncoated finish — no plating to chip, flake, or add dimensional variance to threaded fit
• Socket cap head style allows recessed installation in counterbored holes

Compatibility

Designed as a standard 4-40 UNC hex socket cap screw for use in any application calling for an imperial-threaded, socket-drive cap screw in 18-8 stainless steel with a 7/16 inch under-head length.

Installation Notes

Install with a 3/32 inch hex key or matching hex bit driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling, which is common with stainless steel fasteners. Apply an anti-seize compound if repeated removal is expected. Do not use an impact driver on small-diameter stainless fasteners, as this increases the risk of thread stripping or head rounding.
