Value Collection MSPI0-500500-100BX Machine Screw 5-40

Product Description

The VALUE COLLECTION MSPI0-500500-100BX is a 5-40 x 1/2 inch pan head machine screw with a slotted drive, manufactured from Grade 2 steel with a zinc-plated finish. The pan head profile provides a low-profile, wide-bearing surface suited for sheet metal, light-gauge panels, and general mechanical assemblies. The slotted drive is compatible with standard flat-blade screwdrivers and is a common fastener type found in HVAC equipment, electrical enclosures, plumbing fixtures, and general industrial applications. This fastener meets ANSI B 18.6.7 M, DIN 85, ISO 1580, and JIS B 1101 standards. Sold in a box of 100.

This screw is used in light-duty mechanical and electrical assemblies where a pan head profile and slotted drive are specified. Typical applications include securing panels, brackets, and covers in HVAC units, electrical junction boxes, control cabinets, and plumbing equipment. The 1/2 inch length is measured under the head. The zinc plating provides basic corrosion resistance suitable for indoor and protected environments. This fastener is appropriate for use by electricians, HVAC technicians, plumbers, and general maintenance trades.

Key Features

• 5-40 thread size with 1/2 inch length under head for precise fitment in light-duty assemblies
• Pan head profile provides a wide bearing surface and low-profile seating
• Slotted drive compatible with standard flat-blade screwdrivers
• Grade 2 steel construction for reliable strength in general-purpose applications
• Zinc-plated finish for basic corrosion resistance in indoor environments
• Meets ANSI B 18.6.7 M, DIN 85, ISO 1580, and JIS B 1101 standards

Compatibility

Designed as a general-purpose machine screw for light-duty mechanical and electrical assemblies requiring a 5-40 thread, pan head, and slotted drive configuration without a washer.

Installation Notes

Installation is performed with a standard flat-blade screwdriver sized to fit the slotted head. Always power down electrical equipment and de-energize panels before replacing or installing fasteners in live enclosures, in accordance with applicable NEC guidelines. Do not overtighten; snug to hand-tight plus a quarter turn is appropriate for most light-gauge panel applications. Inspect threads on mating components before installation to avoid cross-threading.
