Hillman Fasteners 80075 Sheet Metal Screw No.10 X 1-1/4 in 100pk

Product Description

The HILLMAN FASTENERS 80075 is a zinc-plated sheet metal screw designed for fastening thin metal panels, HVAC ductwork, electrical enclosures, and light structural sheet metal assemblies. The No. 10 x 1-1/4 inch pan head screw features a Phillips drive and a sharp point for self-starting penetration without pre-drilling in most light-gauge applications. The zinc coating provides basic corrosion resistance suitable for dry or mildly humid indoor environments. Each box contains 100 screws, making it practical for high-volume service calls and shop stock. Licensed trades and maintenance professionals rely on this style of fastener for duct connections, junction box covers, and equipment panel work.

This fastener is a standard choice for residential and light commercial HVAC sheet metal work, including supply and return duct assembly, plenum construction, and equipment access panel attachment. Electricians use pan head sheet metal screws for securing enclosure covers and conduit straps to light-gauge framing. Plumbers and general trades use them for backing plates and mechanical equipment mounting in panel applications. The pan head profile distributes clamping load across a wider surface area than flat-head styles, reducing pull-through risk in thin sheet stock.

Key Features

• No. 10 x 1-1/4 inch size suits common light-gauge sheet metal thicknesses used in HVAC and electrical work
• Phillips pan head drive compatible with standard power and manual screwdrivers
• Zinc plating provides corrosion resistance for indoor and protected installations
• Sharp point allows self-starting penetration in light-gauge sheet metal without pre-drilling
• 100-count pack supports bulk use on service calls and installation projects

Compatibility

Designed as a standard No. 10 x 1-1/4 inch Phillips pan head sheet metal screw suitable for general light-gauge sheet metal fastening applications across HVAC, electrical, and mechanical trades.

Installation Notes

Installation requires no special tools beyond a No. 2 Phillips bit and a power or manual screwdriver. Verify sheet metal gauge and substrate thickness before selecting screw length to ensure adequate thread engagement without breakthrough in tight clearance areas. Avoid over-driving, which can strip threads in thin sheet metal or deform the pan head seating surface. Work performed on energized electrical enclosures or pressurized duct systems should follow applicable NEC or SMACNA safety procedures before fastener work begins.
