Value Collection 0308MSP 3-48 X 0.5 in Pan Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 0308MSP is a 3-48 unified coarse thread machine screw designed for light-duty fastening applications across mechanical assemblies, electrical enclosures, and equipment panels. The pan head profile provides a low, rounded head with a flat bearing surface, and the slotted drive accepts a standard flat-blade screwdriver. Manufactured from steel with a zinc finish, this screw measures 0.5 inches in length under head and conforms to ASME B18.6.3 and SAE J82 dimensional and mechanical standards. It is suited for technicians and assemblers working in HVAC controls, electrical panels, and general trade fabrication where a small-diameter threaded fastener is required.

This screw is appropriate for use in residential and light commercial applications wherever a 3-48 thread form is specified. Typical install scenarios include securing terminal strips, control boards, junction box covers, and sheet-metal panels. The zinc finish provides basic corrosion resistance suitable for indoor and protected environments. This SKU is sold as a single package with a minimum order quantity of 100 pieces, making it practical for service vans, job boxes, and shop stock replenishment.

Installation Notes

Installation is typically performed by electricians, HVAC technicians, or mechanical assemblers using a flat-blade screwdriver or matching bit. De-energize and lock out any electrical equipment before fastening screws into control panels or live enclosures in accordance with NFPA 70 lockout-tagout requirements. Do not overtighten into plastic bosses or thin sheet metal, as the 3-48 thread form is small in diameter and susceptible to strip-out under excessive torque. Verify thread engagement depth matches the tapped hole or nut to ensure full thread contact.
