Value Collection 0524MSRNH 5-40 X 1.5in Round Slotted Machine Screw

Product Description

The VALUE COLLECTION 0524MSRNH is a 5-40 unified coarse thread machine screw designed for general-purpose fastening in light mechanical assemblies, electrical enclosures, and panel work. The round head profile provides a low-profile, domed bearing surface suited to through-hole and clearance-hole applications. The slotted drive accepts a standard flat-blade screwdriver, making it a practical choice in environments where specialized tooling is not available. Manufactured from steel with a zinc finish, this screw meets ASME B18.6.3 and SAE J82 standards. Length under head is 1.5 inches. This fastener is sold individually per package, with a minimum order quantity of 100 pieces.

This screw is used across residential and light commercial applications including electrical panel assembly, HVAC control box mounting, motor junction covers, and general sheet metal or chassis work. The 5-40 thread size is common in small-component fastening where a fine, reliable thread engagement is needed in thin or tapped steel, aluminum, or plastic substrates. Technicians working on control boards, terminal strips, or instrumentation enclosures will find this size and drive combination familiar and widely applicable.

Key Features

• 5-40 unified coarse thread for reliable engagement in light mechanical and electrical assemblies
• Round head profile with slotted drive — compatible with standard flat-blade screwdrivers
• 1.5 inch length under head suits moderate-depth through-hole and tapped applications
• Steel construction with zinc finish provides basic corrosion resistance for indoor service environments
• Meets ASME B18.6.3 and SAE J82 fastener standards
• No washer — bare shank under head for direct bearing on workpiece surface

Compatibility

Designed as an OEM-style replacement or maintenance stock fastener for any application requiring a 5-40 thread, 1.5 inch length-under-head, round head slotted machine screw conforming to ASME B18.6.3 or SAE J82 standards.

Installation Notes

Installation is performed by electricians, HVAC technicians, and mechanical assemblers using a standard flat-blade screwdriver sized to the slot. Always de-energize and lock out electrical equipment before replacing or tightening fasteners in live panels or control enclosures, in accordance with NFPA 70E safe work practices. Do not over-torque into tapped plastic or soft aluminum to avoid stripping threads. Ensure the mating thread is clean and free of debris before driving.
