Value Collection MSPI02504000-100B Machine Screw

Product Description

The VALUE COLLECTION MSPI02504000-100B is a 1/4-20 pan head machine screw with a slotted drive, measuring 4 inches in length under the head. Made from steel with a zinc-plated finish, this fastener meets ASME B18.6.3 and SAE J82 standards. The pan head profile provides a low-profile bearing surface, and the slotted drive is compatible with standard flat-tip screwdrivers. This screw is sold individually per package. Minimum order quantity is 10 units. Suitable for mechanical assembly, electrical enclosures, HVAC equipment panels, and general trade fastening applications requiring a unified coarse thread in inch sizing.

This fastener is used across a range of trade applications including HVAC equipment assembly, electrical panel mounting, plumbing fixture installation, and light structural fastening. The 1/4-20 unified coarse thread pattern is a common size in commercial and residential equipment manufacturing and field service work. The zinc plating provides basic corrosion resistance suitable for indoor and protected outdoor environments. Technicians and mechanics working on metal enclosures, brackets, and equipment frames will find this a standard replacement or general-purpose fastener.

Installation Notes

Installation requires a flat-tip screwdriver or slotted bit driver sized for a 1/4-20 fastener head. Ensure the mating tapped hole or nut is clean and free of debris before driving. Do not overtighten, as this may strip the slotted drive or damage the receiving thread. Power down all equipment before installing or removing fasteners from live electrical or mechanical assemblies.
