Value Collection 0208MSB 2-56 X 1/2 in Binding Head Slotted Screw

Product Description

The VALUE COLLECTION 0208MSB is a binding-head machine screw designed for precision fastening applications in electrical, electronic, and light mechanical assemblies. This screw features a 2-56 thread size with a 1/2-inch length under head measurement, a slotted drive, and a zinc finish over steel construction. The binding head profile provides a low-profile, wide-bearing surface that resists pull-through in sheet metal and panel work. It conforms to ASME B18.6.3 and SAE J82 standards, making it suitable for controlled-tolerance installations where dimensional consistency matters. Trades professionals in electrical and electronics work reach for this screw when securing terminal blocks, panel components, and instrumentation hardware.

This machine screw is used in residential and commercial applications wherever small-diameter, fine-thread fasteners are required. Typical install scenarios include control panel assembly, low-voltage wiring device mounting, and light-gauge enclosure work. The 2-56 thread is a standard size in electrical and electronic instrument assembly, fitting tapped holes in aluminum, steel, and thermoplastic housings. This SKU is sold as a single package with a minimum order quantity of 100 pieces, appropriate for shop stock or job-lot purchasing.

Compatibility

Designed as an OEM-style replacement or stock fastener for applications requiring a 2-56 UNC binding-head slotted machine screw per ASME B18.6.3 and SAE J82 specifications.

Installation Notes

Installation is typically performed by electricians, electronics technicians, or mechanical assemblers using a flat-blade screwdriver sized to the slotted head. Always ensure the mating tapped hole is clean and properly formed to 2-56 UNC specifications before driving the screw to avoid cross-threading. Do not over-torque small-diameter machine screws into tapped thermoplastic or thin sheet metal, as thread stripping can occur. Follow applicable NEC or equipment manufacturer guidelines for fastener torque requirements in electrical enclosures.
