Value Collection 1516MSP 1/4-28x1 Pan Head Slotted Screw

Product Description

The VALUE COLLECTION 1516MSP is a 1/4-28 unified fine thread machine screw with a pan head and slotted drive, manufactured from steel with a zinc-plated finish. This fastener measures 1 inch in length under the head and is built to ASME B18.6.3 and SAE J82 standards, confirming dimensional accuracy and material grade compliance. The zinc plating provides baseline corrosion resistance suitable for general indoor mechanical and electrical applications. Electricians, HVAC technicians, plumbers, and general tradespeople use this style of fastener for panel assembly, equipment mounting, and component attachment where a low-profile pan head and simple slotted drive are appropriate.

This screw is suited for light to medium-duty fastening tasks in residential and commercial trade work. The 1/4-28 fine thread pitch provides tighter thread engagement compared to coarse thread variants, making it a common choice for metal-to-metal joints where vibration resistance or precise torque control matters. Typical applications include control panel assembly, electrical enclosure work, HVAC equipment access covers, and general mechanical assembly in shop or field environments.

Key Features

• 1/4-28 unified fine thread for tight thread engagement in metal applications
• Pan head profile keeps a low, broad bearing surface without sharp edges
• Slotted drive compatible with standard flathead screwdrivers
• Zinc-plated steel finish for basic corrosion resistance
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• No washer — fastens directly without an integrated washer flange

Compatibility

Designed as a standard 1/4-28 x 1 inch pan head slotted machine screw for general-purpose use in electrical, HVAC, plumbing, and mechanical assembly applications where this thread size and head style are specified.

Installation Notes

Installation requires a flathead screwdriver or slotted bit sized for a 1/4-inch pan head fastener. Always de-energize electrical equipment before fastening or removing screws on live panels or enclosures, following applicable NEC lockout/tagout procedures. Do not overtighten into tapped holes in thin sheet metal, as fine threads can strip under excessive torque. Inspect threads and mating holes for damage or debris before installation.
