Value Collection R40662428 Hex Socket Cap Screw 2-56 Unc

Product Description

The VALUE COLLECTION R40662428 is a 2-56 UNC hex socket cap screw used to fasten components in tight spaces where a standard hex wrench or Allen key is required. Machined from 18-8 stainless steel, this fastener delivers reliable corrosion resistance in both indoor and outdoor assemblies. The 5/64-inch hex drive socket accepts a standard hex key, and the 0.25-inch length under head suits thin-material clamping applications. This screw is appropriate for use by electricians, mechanical technicians, and instrumentation professionals working with small-gauge fastening requirements.

This cap screw is suited for light-duty mechanical assemblies, electrical enclosure panel mounting, instrumentation brackets, and precision equipment where a No. 2-56 thread pattern is specified. The 18-8 stainless steel construction makes it suitable for environments where mild corrosion resistance is needed. It is well-matched to applications in HVAC controls, electrical panels, and similar trade equipment requiring small-diameter machine screws.

Key Features

• 2-56 UNC thread size for precise, fine-thread fastening in small components
• 5/64-inch hex socket drive accepts a standard hex key or Allen wrench
• 0.25-inch length under head suits thin-stock clamping applications
• 18-8 stainless steel construction provides corrosion resistance without plating
• Socket cap head style allows use in recessed or countersunk mounting holes

Compatibility

Designed as a standard 2-56 UNC hex socket cap screw suitable for any application specifying a No. 2-56 thread, 0.25-inch length under head, and a 5/64-inch hex drive in 18-8 stainless steel.

Installation Notes

Installation requires a 5/64-inch hex key or Allen wrench. Always power down or de-energize any electrical assembly before installing or removing fasteners in panel or enclosure applications. Avoid over-torquing small-diameter screws, as 2-56 fasteners have low cross-sectional area and are susceptible to thread stripping. Handle with care to avoid cross-threading, especially in tapped aluminum or plastic substrates.
