Value Collection R40662141 Hex Socket Cap Screw 2-56 Unc

Product Description

The VALUE COLLECTION R40662141 is a 2-56 UNC hex socket cap screw designed for precision fastening in tight-clearance assemblies. Machined from 18-8 stainless steel, this screw delivers solid corrosion resistance and mechanical strength in a compact form. The 5/64-inch hex drive accepts a standard hex key or Allen driver for reliable torque transfer without fastener damage. With a 1-inch length under the head, this screw suits shallow-to-moderate depth threaded applications where a clean, low-profile cap head is required. This style of fastener is standard in instrumentation, panel assembly, and light mechanical assembly work.

This fastener is appropriate for use in light-duty mechanical assemblies, instrument enclosures, electrical panels, and equipment frames where a fine-thread 2-56 UNC pattern is specified. The 18-8 stainless steel construction makes it suitable for indoor or mildly corrosive environments. It is commonly specified by mechanical assemblers, electricians, and maintenance technicians working on control enclosures, sensor mounts, and small-form-factor brackets.

Key Features

• 2-56 UNC thread form for fine-pitch engagement in small threaded holes
• 5/64-inch hex socket drive for precise torque application with standard hex keys
• 1-inch length under head accommodates moderate material stack depths
• 18-8 stainless steel construction provides corrosion resistance in mild environments
• Low-profile socket cap head design suits flush or recessed installation

Compatibility

Designed as a standard 2-56 UNC hex socket cap screw for use in any threaded assembly or tapped hole specifying a 2-56 UNC fine thread pattern and a 1-inch length under head.

Installation Notes

Install using a 5/64-inch hex key or Allen driver. Ensure the mating threaded hole or nut is clean and free of debris before fastening. Do not over-torque small-diameter stainless fasteners, as galling can occur; applying an appropriate anti-seize compound is recommended in stainless-to-stainless thread engagement. Power down any electrical equipment before accessing panels or enclosures where this fastener is used.
