Value Collection R40662401 Hex Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION R40662401 is a hex socket cap screw designed for secure, high-torque fastening in tight-clearance applications. Threaded to a 2-56 UNC specification, it measures 0.5 inches in length under the head and accepts a 5/64-inch hex drive. Constructed from 18-8 stainless steel, this screw resists corrosion in moisture-exposed environments. It is suited for precision mechanical assemblies, instrumentation enclosures, electrical panels, and light industrial equipment. Machinists, maintenance technicians, and assembly professionals use this fastener where a small-diameter, fine-pitch cap screw is required.

This screw is used in applications calling for a no. 2 machine screw thread pattern in ferrous and non-ferrous assemblies. Typical installations include instrument mounting, small-gauge electrical terminal assemblies, and precision component fixturing. The 18-8 stainless steel construction makes it appropriate for indoor and moderate outdoor environments where mild corrosion resistance is needed. It is not intended for high-temperature or heavy-structural load applications. Sold individually; minimum order quantity is 100 pieces per order placement.

Key Features

• 2-56 UNC thread for fine-pitch, small-diameter fastening requirements
• 0.5-inch length under head accommodates shallow-to-medium stack assemblies
• 5/64-inch hex drive for use with standard hex keys or Allen drivers
• 18-8 stainless steel construction provides corrosion resistance in moisture-present environments
• Low profile cap head design suits recessed or flush-mount fastening scenarios

Compatibility

Designed as a standard 2-56 UNC hex socket cap screw suitable for precision mechanical assemblies, instrumentation hardware, and electrical enclosures requiring a no. 2 machine screw thread form.

Installation Notes

Installation is performed by machinists or maintenance technicians using a calibrated 5/64-inch hex key or Allen driver. Ensure mating threads are clean and free of debris before driving. Avoid cross-threading by starting the screw by hand before applying torque. Stainless fasteners are susceptible to galling when driven at excessive speed; use a hand driver or low-speed setting on power tools.
