Value Collection 31947 Hex Head Sheet Metal Screw 25 Pack

Product Description

The VALUE COLLECTION 31947 is a 5/16-inch hex head sheet metal screw designed for fastening thin metal substrates in HVAC, electrical, and general sheet metal fabrication work. Built from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this screw measures 1.5 inches in length under the head. The Type A point provides self-starting penetration into light-gauge sheet metal without pre-drilling. Drive engagement is hex, suiting standard nut drivers and socket sets common in HVAC and sheet metal trades. This package contains 25 screws.

This screw is suited for residential and light commercial sheet metal applications including duct assembly, junction box attachment, metal panel fastening, and equipment enclosure work. HVAC technicians and sheet metal workers commonly use Type A hex head screws when a flush-free, high-torque drive is required. The hex head allows for consistent torque application with a nut driver, which is standard practice in duct and equipment panel installation.

Key Features

• 5/16-inch thread size for secure engagement in light-gauge sheet metal
• 1.5-inch length under head for adequate bite through stacked sheet metal layers
• Type A self-starting point eliminates the need for pre-drilling in most light-gauge applications
• Hex head and hex drive allow high-torque installation with standard nut drivers
• Grade 2 steel construction provides reliable tensile strength for general fastening duty
• Zinc-plated finish offers basic protection against corrosion in typical indoor environments

Compatibility

Designed as a standard Type A hex head sheet metal screw for use in light-gauge metal fastening applications typical of HVAC ductwork, electrical enclosures, and general sheet metal fabrication.

Installation Notes

Installation is performed by HVAC technicians, electricians, and sheet metal workers using a standard nut driver or hex socket. Ensure the workpiece is secured and de-energized before fastening near electrical components. Do not overdrive — stop when the head seats flush to avoid stripping the sheet metal. Follow applicable local codes and manufacturer guidelines for fastener spacing on duct assemblies.
