Tradepro tp-7x1/2tpm Hex Washer Head Screw Zinc 1000ct

Product Description

The TRADEPRO tp-7x1/2tpm is a No. 7 by 0.5-inch hex washer head sheet metal screw with a sharp sprint point tip and zinc plating, sold in a 1000-count pack. Twin lead threads reduce driving torque, which speeds up installation on repetitive fastening tasks. The actual screw body measures approximately 9/16 inches in length, providing greater thread engagement than the nominal dimension suggests. These screws are well suited for light-gauge metal assembly work common in HVAC ductwork fabrication, electrical panel work, and general trade construction. Zinc plating provides corrosion resistance for both indoor and exposed applications.

This screw is used wherever a self-starting hex washer head fastener is needed in light sheet metal, thin steel, or similar substrates. The sprint point tip self-pierces without a pilot hole in compatible gauges, making it a go-to fastener for duct assembly, electrical enclosure work, and HVAC equipment panels. The 1000-count pack is sized for shop stock or job-site supply where high-volume fastening is routine.

Key Features

• No. 7 by nominal 0.5-inch size with actual 9/16-inch body length for deeper thread engagement
• Twin lead threads reduce driving torque and speed up installation
• Sprint point tip self-starts in light-gauge sheet metal without a pilot hole
• Hex washer head provides a positive drive surface and acts as an integral washer
• Zinc plating resists corrosion in standard indoor and light-exposure environments
• 1000-count pack suited for high-volume trade use

Compatibility

Designed for use with light-gauge sheet metal substrates typical in HVAC ductwork, electrical enclosures, and general trade metal fabrication applications.

Installation Notes

Install with a hex driver bit matched to the fastener head size. Verify substrate gauge compatibility before use, as sprint point screws are rated for light-gauge metal and may not self-pierce heavier stock. Power down any electrical equipment before fastening near live components. Follow applicable NEC or local code requirements when fastening within electrical enclosures.
