Value Collection SMPTI-1400750-050B No. 14 Sheet Metal Screw

Product Description

The VALUE COLLECTION SMPTI-1400750-050B is a No. 14 sheet metal screw with a truss head and Phillips drive, sold in a minimum quantity of 50 pieces. Built from Grade 2 steel with a zinc finish, this screw is designed for fastening sheet metal components in HVAC ductwork, electrical enclosures, and light-gauge metal fabrication. The truss head provides a wide, low-profile bearing surface that resists pull-through in thin materials. The Type A point self-taps into pre-drilled or punched sheet metal without requiring a separate nut. The 3/4-inch length is measured under the head per standard fastener convention.

This screw is commonly used by HVAC technicians assembling or field-modifying sheet metal ductwork, as well as electricians securing junction box covers and light sheet metal panels. The Phillips drive is compatible with standard screwdrivers and power drivers, making it a practical choice for high-volume fastening tasks on the job site or in the shop. The zinc finish provides basic corrosion resistance suitable for indoor and sheltered applications.

Key Features

• No. 14 thread size for reliable bite in light-gauge sheet metal
• Truss head profile offers a wide bearing surface to reduce pull-through
• Phillips drive compatible with standard and power screwdrivers
• Type A self-tapping point eliminates the need for a pre-tapped hole
• Grade 2 steel construction with zinc finish for corrosion resistance
• 3/4-inch length under head suits typical sheet metal panel thicknesses

Compatibility

Designed as a general-purpose sheet metal fastener suitable for light-gauge steel panels, HVAC ductwork connections, and electrical enclosure assemblies where a No. 14 truss head Phillips screw is specified.

Installation Notes

Installation is performed with a Phillips-head screwdriver or power driver set to a controlled torque to avoid stripping the drive or overdriving into thin sheet metal. Ensure the base material is properly supported before driving to prevent deformation. Follow applicable codes such as SMACNA standards for ductwork fastener spacing when used in HVAC duct assembly. Avoid use in outdoor or high-moisture environments where the zinc finish may be insufficient for long-term corrosion protection.
