Value Collection 0414MSP 4-40 X 7/8 in Pan Head Slotted Screw

Product Description

The VALUE COLLECTION 0414MSP is a 4-40 UNC pan head machine screw designed for precision fastening applications in light mechanical assemblies. The slotted drive accepts a standard flat-blade screwdriver. The screw measures 7/8 inch in length under the head and is manufactured from steel with a zinc finish for basic corrosion resistance. Grade J82 designates the mechanical property class per SAE and ASME standards. These fasteners are ordered in multiples of 100, making them a practical choice for production runs, service kits, and bench stock replenishment by mechanical assemblers, HVAC technicians, and electricians.

This screw is suited for use in sheet metal enclosures, control panels, electrical boxes, and small mechanical assemblies where a #4-40 threaded hole or nut is required. The pan head profile provides a wide bearing surface with a low-profile dome, appropriate for flush or near-flush fastening in tight clearance areas. Applications span residential and light commercial equipment assembly and repair where #4-40 hardware is specified.

Key Features

• 4-40 UNC thread size for use in standard #4-40 tapped holes and nuts
• 7/8 inch length under head for typical light-assembly clamping depth
• Pan head profile provides broad bearing surface and low-profile dome
• Slotted drive compatible with standard flat-blade screwdrivers
• Zinc finish on steel construction for basic corrosion protection
• Meets ASME B18.6.3 and SAE J82 fastener standards

Compatibility

Designed as a standard inch-series machine screw for any assembly or repair application specifying a 4-40 UNC pan head slotted fastener per ASME B18.6.3.

Installation Notes

Install using a flat-blade screwdriver sized to fit the slotted head. De-energize and lock out any electrical or mechanical equipment before replacing fasteners in live panels or assemblies. Do not overtighten into plastic or soft-metal bosses, as #4-40 threads in thin materials strip easily. Follow applicable assembly specifications for torque requirements.
