Value Collection R63068320 2-56 X 1/4 in Pan Head Screw

Product Description

The VALUE COLLECTION R63068320 is a 2-56 x 1/4 inch pan head machine screw designed for precision fastening in light-duty mechanical assemblies. Manufactured from grade 18-8 stainless steel with a bright, uncoated finish, this screw delivers solid corrosion resistance in environments where moisture or mild chemicals may be present. The slotted drive accepts a standard flat-blade screwdriver, making it straightforward to install and remove with common hand tools. The length measurement is taken from under the head, with a length under head of 1/4 inch. This fastener follows inch-system threading with a UNC 2-56 thread specification and ships without a washer.

This machine screw is suited for use in electrical enclosures, control panels, instrument housings, and small mechanical assemblies where a compact, corrosion-resistant fastener is required. Electricians, panel builders, and instrumentation technicians commonly use 2-56 fasteners to secure terminal covers, circuit boards, and lightweight brackets. The pan head profile distributes clamping load across a wider bearing surface compared to flat head styles, making it appropriate for thin sheet metal and plastic substrates.

Key Features

• Grade 18-8 stainless steel construction provides corrosion resistance in humid or mildly corrosive environments
• 2-56 UNC thread form ensures compatibility with standard inch-series tapped holes and nuts
• Pan head profile offers a wide bearing surface suitable for thin sheet metal and plastic
• Slotted drive accommodates standard flat-blade screwdrivers for easy installation and removal
• Bright, uncoated finish maintains dimensional accuracy without added plating thickness
• No washer included — length under head is 1/4 inch for precise fitment in close-tolerance applications

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 2-56 UNC thread, including tapped holes, hex nuts, and nylon insert locknuts dimensioned to the 2-56 thread specification.

Installation Notes

Installation requires a flat-blade screwdriver sized to the slotted head. Verify that the mating tapped hole or nut is threaded to 2-56 UNC before driving the fastener. De-energize and lock out any electrical panel or control board before accessing fastener locations within live enclosures, in accordance with NFPA 70E safe work practices. Avoid over-torquing — the small diameter of a no. 2 screw is susceptible to thread stripping in softer base materials such as aluminum or plastic.
