Value Collection SPTCIF0-400750-100BX 4-40 Unc Screw 100pk

Product Description

The VALUE COLLECTION SPTCIF0-400750-100BX is a 4-40 UNC thread cutting screw designed for reliable fastening in light-duty metal and plastic assemblies. It features a pan head profile, slotted drive, and a Type F point that cuts its own mating thread as it is driven, eliminating the need for a pre-tapped hole in many applications. Constructed from Grade 2 steel with a zinc-plated finish, it provides basic corrosion resistance suitable for indoor and controlled-environment use. The 3/4-inch length under head accommodates moderate material stack-ups. This fastener is sold in a box of 100 pieces and is commonly handled by HVAC technicians, electricians, and sheet metal workers.

This screw is suited for light sheet metal fabrication, electrical enclosure assembly, control panel construction, and HVAC equipment housing work. The 4-40 UNC thread size is a standard fine-pitch designation common in small instrument panels, electrical junction boxes, and equipment chassis. The Type F point style makes it particularly useful where tapping a pilot hole separately is impractical. It is appropriate for residential and light commercial trade applications where a small-diameter, self-threading fastener is required.

Key Features

• Type F thread cutting point drives into metal without a pre-tapped hole
• Pan head profile provides a low-profile bearing surface and wide clamping area
• Slotted drive compatible with standard flat-blade screwdrivers and power drivers
• Grade 2 steel construction for reliable tensile strength in light-duty fastening
• Zinc-plated finish for basic corrosion protection in indoor environments
• Sold in a box of 100 pieces to support production and service work

Compatibility

Designed as a standard 4-40 UNC thread cutting fastener suitable for light-gauge sheet metal, electrical enclosures, and equipment chassis assemblies where a Type F point self-threading screw is specified.

Installation Notes

Installation is typically performed by electricians, HVAC technicians, or sheet metal workers using a flat-blade screwdriver or appropriately sized power driver bit. Ensure the pilot hole diameter is sized correctly for the material thickness and hardness to achieve proper thread engagement without splitting or stripping. Do not overtorque small-diameter screws such as 4-40, as the reduced thread section is susceptible to shear under excessive torque. Follow applicable NEC or equipment manufacturer guidelines when fastening within electrical enclosures.
