Value Collection -33828-1/2 No.6 Self Drilling Screw

Product Description

The VALUE COLLECTION -33828-1/2 is a No. 6 self drilling screw designed for fast, reliable fastening in light-gauge metal and sheet metal applications. Built from 1016-1024 grade steel with a zinc-plated finish, this screw drills its own pilot hole and taps its own thread in a single operation, eliminating pre-drilling steps. The hex washer head provides a built-in bearing surface that distributes clamping load, and the hex drive accepts standard hex or nut driver bits for consistent torque application. At 0.5 inches length under head with a No. 2 drill point, it is sized for thin-material work common in HVAC, electrical enclosure, and light mechanical assembly tasks.

This screw is suited for residential and commercial trade applications where sheet metal panels, ductwork flanges, electrical enclosures, or equipment housings need to be joined without pre-drilled holes. HVAC technicians commonly use No. 6 self drilling screws with hex washer heads when securing duct collars, access panels, and unit covers. Electricians use them on enclosure knockouts and junction box covers. The zinc-plated coating provides basic corrosion resistance in dry or moderately humid indoor environments.

Key Features

• No. 2 drill point self-taps and drills in one pass — no pilot hole required
• Hex washer head distributes clamping load and resists pull-through in light-gauge material
• Hex drive accepts standard nut driver or hex bit for fast installation with a power tool
• 1016-1024 grade steel construction meets AISI, ASME B18.6.3, and SAE J78 standards
• Zinc-plated finish provides corrosion resistance in dry indoor environments
• 0.5 inches length under head suits thin sheet metal and panel fastening applications

Compatibility

Designed as a standard No. 6 hex washer head self drilling screw for use in light-gauge sheet metal, HVAC ductwork panels, electrical enclosures, and similar thin-material assemblies.

Installation Notes

Installation is performed with a hex driver bit or nut driver matched to the hex head size, typically using a variable-speed power drill or screw gun. No pre-drilling is required for light-gauge material within the No. 2 drill point capacity range. Avoid over-driving — strip-out of the self-tapped thread is the most common installation error with self drilling screws in thin stock. Confirm material thickness is appropriate for the selected drill point and screw length before driving.
