Value Collection SPTCIF0-400180-100BX 4-40 Unc Screw 100pk

Product Description

The VALUE COLLECTION SPTCIF0-400180-100BX is a 4-40 UNC thread cutting screw designed for use in light-gauge metal and pre-tapped or self-tapped holes where a secure, vibration-resistant fastener is needed. The pan head profile sits low against the work surface and distributes clamping load evenly. A slotted drive accepts standard flat-blade screwdrivers or bit-tip drivers. The Type F point features a cutting edge that taps its own thread on the way in, eliminating the need for a pre-cut thread in many thin-metal applications. Zinc plating provides a basic level of corrosion resistance for indoor and light-duty environments. This 100-piece box suits production-line or service-shop use.

These screws are a common fastener in HVAC cabinet assembly, electrical enclosure fabrication, control panel mounting, and sheet metal work across residential and light commercial applications. Electricians, HVAC technicians, and sheet metal workers keep these on hand for securing cover panels, mounting brackets, and terminal blocks to thin steel substrates. The 4-40 UNC thread is a standard machine screw size widely used in instrument and control hardware, making this screw a practical stock item for service vans and shop benches alike.

Key Features

• 4-40 UNC thread size — standard machine screw sizing compatible with 4-40 tapped hardware
• 3/16 inch length under head for use in thin-gauge panels and covers
• Type F point cuts its own thread path in thin metal, reducing assembly steps
• Pan head profile with slotted drive — works with flat-blade screwdrivers and standard bit drivers
• Grade 2 steel construction with zinc plating for indoor and light-duty corrosion resistance
• Sold in a 100-piece minimum order quantity for production and service shop stocking

Compatibility

Designed as a general-purpose 4-40 UNC thread cutting fastener suitable for thin-gauge steel panels, electrical enclosures, HVAC cabinet assemblies, and control hardware where a Type F point thread cutting screw is specified.

Installation Notes

Installation is performed with a flat-blade screwdriver or matching slotted bit driver; avoid power driving at high torque settings to prevent stripping the slotted recess or over-driving into thin material. The Type F point is intended for use in drilled pilot holes sized to the screw's minor diameter — consult a standard tap-drill chart for the correct pilot hole size in the specific material thickness. Always de-energize electrical enclosures and panels before installing or removing fasteners near live components, following applicable NEC lockout-tagout procedures.
