Value Collection 0303MSB 3-48 Binding Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 0303MSB is a 3-48 binding head machine screw designed for precision fastening applications in electrical, electronic, and light mechanical assemblies. The binding head profile provides a low-profile, broad-bearing surface that resists pull-through in thin materials. Finished in zinc for basic corrosion resistance, this screw is manufactured from steel to Grade J82 and conforms to ASME B18.6.3 and SAE J82 standards. The slotted drive accommodates a standard flat-blade screwdriver, making it a common choice for panel, terminal, and fixture work where a simple tool interface is preferred.

This screw is suited for residential and commercial electrical panel assembly, electronic enclosures, instrumentation housings, and light sheet-metal or plastic fixture work. The 3-48 thread size is frequently encountered in terminal strip mounting, small appliance assembly, and control board retention. Installation requires no power tools; hand-driving with a flat-blade screwdriver is the standard method. The binding head style is specified where a washer-style seat is not required and a clean, flush look against the work surface is preferred.

Installation Notes

Installation is performed with a flat-blade screwdriver sized to the slotted drive. Power down or de-energize any assembly before fastening screws into electrical enclosures or control panels, following applicable NEC requirements. Avoid over-torquing the 3-48 thread, as the small diameter is susceptible to thread stripping in soft substrates such as plastic or thin aluminum. Confirm the tapped hole thread class matches a standard 3-48 UNC specification before installation.
