Value Collection 0505MSR 5-40 X 5/16 in Round Head Slotted Screw

Product Description

The VALUE COLLECTION 0505MSR is a 5-40 UNC machine screw with a round head and slotted drive, intended for light-duty mechanical assembly and equipment maintenance applications. The screw measures 5/16 inches in length under the head and is manufactured from steel with a zinc finish for basic corrosion resistance. It conforms to ASME B18.6.3 and SAE J82 standards, ensuring dimensional consistency across production runs. This fastener is a common choice for technicians and tradespeople who need a reliable, standardized screw for panel attachment, instrument housings, and similar close-tolerance applications.

The 0505MSR is suited for residential and commercial maintenance environments where small-diameter machine screws are required. It is commonly used in HVAC equipment panels, electrical enclosures, plumbing fixture assemblies, and general equipment service work. The slotted drive is compatible with standard flathead screwdrivers, making it accessible in field service conditions. This item is sold in a package quantity of one lot with a minimum order quantity of 100 pieces.

Key Features

• 5-40 UNC thread size for compatibility with standard tapped holes in light-gauge hardware
• Round head profile provides a low-profile, finished appearance on exposed surfaces

• Steel construction with zinc finish for baseline corrosion protection
• Conforms to ASME B18.6.3 and SAE J82 fastener standards
• Consistent length under head of 5/16 inches for predictable clamp depth

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 5-40 UNC thread, round head, slotted drive fastener per ASME B18.6.3 and SAE J82 specifications.

Installation Notes

Install using a standard flathead screwdriver sized to the slot width to avoid cam-out and slot damage. Ensure the mating tapped hole or nut is clean and free of debris before driving the screw. Do not overtighten — small-diameter machine screws are susceptible to thread stripping in thin or soft base materials. Follow applicable mechanical codes and equipment manufacturer torque guidance where specified.
