Value Collection 0403MSB 4-40 X 3/16 in Binding Head Slotted Screw

Product Description

The VALUE COLLECTION 0403MSB is a 4-40 binding head machine screw designed for use in precision fastening applications where a low-profile, broad-bearing head is required. The slotted drive accepts a standard flat-blade screwdriver. The fastener is manufactured from steel with a zinc-plated finish that provides corrosion resistance for general indoor and light-duty applications. At 3/16 inches in length under the head and threaded to the 4-40 UNC specification, this screw is sized for small-clearance assemblies. It conforms to ASME B18.6.3 and SAE J82 dimensional and material grade standards.

This fastener is suited for light mechanical assemblies, electrical enclosures, control panels, instrumentation mounting, and similar applications where a 4-40 thread is specified. The binding head geometry provides a wider bearing surface than a round or pan head, making it well-suited for securing thin materials or components where pull-through resistance is a consideration. These screws are sold in multiples of 100 units per order.

Compatibility

Designed as a standard 4-40 UNC binding head machine screw for use in any application specifying ASME B18.6.3 compliant fasteners in the 4-40 thread family.

Installation Notes

Installation requires a flat-blade screwdriver sized for a 4-40 screw head. De-energize any electrical assemblies before installing or removing fasteners in control panels or enclosures. Do not overtighten — small-diameter machine screws are susceptible to thread stripping in soft or thin parent materials. Follow applicable assembly drawings and torque specifications provided by the equipment manufacturer.
