Value Collection R52000829 No. 4 Sheet Metal Screw

Product Description

The VALUE COLLECTION R52000829 is a No. 4 hex washer head sheet metal screw designed for fastening light-gauge sheet metal, HVAC ductwork, electrical enclosures, and similar thin-material assemblies. The slotted drive accepts a standard flat-blade screwdriver or power bit, and the Type AB point form threads on first contact without a pre-drilled pilot hole in most light-gauge applications. Manufactured from Grade 1016-1024 steel with a zinc-plated finish, the screw resists corrosion in typical indoor mechanical environments. Length under head measures 0.75 inches, making it well suited for shallow panel and sheet connections where thread engagement depth is limited.

This screw is a standard fastener used across residential and light commercial trade work. HVAC technicians reach for No. 4 hex washer head screws when securing duct sections, access panels, and equipment covers. Electricians use them on sheet metal enclosures, junction boxes, and equipment mounting. The hex washer head provides a positive wrench or nut-driver grip and a built-in bearing surface that distributes clamping load across thin material without requiring a separate washer. Sold in multiples of 100 per minimum order.

Key Features

• Type AB point self-taps into light-gauge sheet metal without a pre-drilled pilot hole in many applications
• Hex washer head accepts a nut driver or hex bit driver for fast installation
• Slotted drive provides a secondary flat-blade screwdriver option in the field
• Grade 1016-1024 steel construction meets AISI, ASME B18.6.3, ASME B18.6.4, and SAE J933 standards
• Zinc-plated finish provides corrosion resistance in standard indoor mechanical environments
• 0.75-inch length under head suits shallow sheet metal connections and panel work

Compatibility

Designed as a standard No. 4 hex washer head Type AB sheet metal screw for use in light-gauge sheet metal fastening applications across HVAC, electrical, and general sheet metal fabrication work.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, or sheet metal workers using a nut driver, hex bit, or flat-blade screwdriver. Verify base material gauge and hardness before driving without a pilot hole, as very hard or thick stock may require a pre-drilled clearance hole to avoid screw breakage. Do not overtorque small-diameter sheet metal screws, as thread stripping in the base material is a common failure mode. Follow applicable codes such as the NEC or SMACNA duct construction standards for fastener spacing and pattern requirements.
