Value Collection MSPI03100620-100B Screw 5/16-18 Pan Head

Product Description

The VALUE COLLECTION MSPI03100620-100B is a 5/16-18 x 5/8 inch pan head machine screw with a slotted drive, manufactured from steel with a zinc-plated finish. Sold in a minimum quantity of 100 pieces, these fasteners meet ASME B18.6.3 and SAE J82 standards, making them suitable for general-purpose mechanical assembly in trade and industrial applications. The zinc plating provides basic corrosion resistance for indoor and sheltered environments. Length is measured under the head at 5/8 inch, and the screws ship without a washer. These are a reliable stock fastener for electricians, HVAC technicians, plumbers, and general contractors who need a compliant, standardized threaded fastener in quantity.

These machine screws are suited for light to medium-duty fastening applications across residential and commercial trades. Common uses include panel mounting, equipment enclosures, junction boxes, HVAC equipment covers, and general sheet metal or machined-surface assembly. The 5/16-18 Unified Coarse thread pitch is widely used in standard American fastener applications, offering broad compatibility with pre-tapped holes and standard hex nuts or coupling nuts of the same thread specification.

Key Features

• 5/16-18 Unified Coarse thread, 5/8 inch length under head
• Pan head profile with slotted drive for standard flat-blade or power driver use
• Steel construction with zinc-plated finish for basic corrosion resistance
• Meets ASME B18.6.3 and SAE J82 fastener standards
• Sold in 100-piece minimum order quantity for trade-volume use
• No washer included; length measurement taken under the head

Compatibility

Designed for use with 5/16-18 tapped holes, hex nuts, and coupling nuts conforming to standard Unified Coarse thread specifications in inch-measurement fastener applications.

Installation Notes

Installation is appropriate for any trade professional performing mechanical assembly with standard threaded fasteners. Ensure the mating hole or nut is clean, free of debris, and matches the 5/16-18 thread specification before driving. Do not overtighten, as pan head fasteners have limited bearing surface compared to flanged or washer-head styles. Follow applicable equipment manufacturer torque guidelines when fastening electrical enclosures or HVAC panels.
