Hillman Fasteners 560330 Self Drilling Screw 100 Pack

Product Description

The HILLMAN FASTENERS 560330 is a No. 10 x 0.75 inch zinc plated hex washer head self drilling screw, sold in a 100-piece pack. Self drilling screws eliminate the need for a pilot hole, combining the drill bit and fastener in a single step. The hex washer head provides a broad bearing surface and is driven with a standard hex driver or nut driver. The zinc plating offers corrosion resistance for general indoor and light outdoor applications. These fasteners are commonly used by HVAC technicians, sheet metal workers, electricians, and general contractors for attaching light-gauge metal panels, ductwork, and enclosures.

The 560330 is suited for light-gauge sheet metal fabrication and assembly tasks encountered in HVAC duct installation, electrical enclosure work, and general metal-to-metal or metal-to-substrate fastening. The hex washer head style is compatible with standard hex drivers and power tools, making installation fast in production or field service environments. The 100-piece pack quantity is appropriate for service van stocking or small project use.

Installation Notes

Self drilling screws are installed by HVAC technicians, sheet metal workers, and electricians using a hex driver bit in a power drill or screw gun. Confirm the base material gauge is within the rated drilling capacity of the screw point before driving. Do not overdrive hex washer head screws, as excess torque can strip the head or distort the material. Follow applicable codes such as SMACNA duct construction standards where fastener type and spacing are specified.
