Value Collection 1456MSP Machine Screw 1/4-20 X 3.5 in Pan Head

Product Description

The VALUE COLLECTION 1456MSP is a 1/4-20 x 3.5-inch pan head machine screw designed for general-purpose mechanical fastening applications. The slotted drive accepts a standard flat-blade screwdriver, making it a practical choice for maintenance and assembly work. Constructed from steel with a zinc-plated finish, this fastener resists corrosion in light-duty environments. It meets ASME B18.6.3 and SAE J82 standards, confirming dimensional accuracy and material grade compliance. Length is measured under the head at 3.5 inches. This fastener is used by HVAC technicians, plumbers, electricians, and general maintenance professionals wherever a reliable 1/4-20 threaded fastener is required.

This machine screw is suited for residential and light commercial equipment assembly, panel mounting, enclosure fabrication, and component attachment. Pan head geometry provides a low-profile bearing surface across a wide range of materials. The slotted drive style is well established in legacy equipment and panel-box hardware, making it a common replacement option in the field. No washer is included or required under the head per standard specification.

Installation Notes

Install using an appropriately sized flat-blade screwdriver. Do not overtighten, as excessive torque may strip the slotted drive or damage the mating thread. Verify that the receiving material thread type matches 1/4-20 UNC before installation. Electricians and HVAC technicians should de-energize equipment before accessing any panel or enclosure fasteners per NFPA 70E safe work practice guidelines.
