Hillman Fasteners 116127 Self-drilling Metal Screw 60ct

Product Description

The HILLMAN FASTENERS 116127 is a hex washer head self-drilling metal screw designed for fast, secure fastening in metal applications without pre-drilling. Sized at 12-24 x 1.5 inches and rated at 11 gauge, this screw features a self-drilling tip that penetrates metal up to 1/8 inch thick in a single step. The star drive recess paired with a Pro-Stick bit design reduces cam-out and improves driver stability during installation. Each box contains 60 screws. This fastener is suited for sheet metal work, HVAC ductwork, light structural assembly, and similar trade applications where speed and holding strength in metal are priorities.

This screw is appropriate for light-gauge metal fastening tasks common in HVAC, electrical, and general mechanical contracting work. The self-drilling tip eliminates the need for a separate pilot hole, reducing tool changes and labor time on the job. The hex washer head provides a wide bearing surface that resists pull-through in thin sheet metal. The 60-count package quantity supports both single-task jobs and ongoing service work.

Key Features

• Self-drilling tip penetrates metal up to 1/8 inch thick with no pre-drilling required
• Star drive recess with Pro-Stick bit design minimizes cam-out and improves driving stability
• Hex washer head provides broad bearing surface to resist pull-through
• 11 gauge wire diameter for adequate shear and tensile strength in light-gauge metal
• 12-24 thread form for positive engagement in sheet metal
• 60 screws per box for efficient stocking and job-site use

Compatibility

Designed for use in light-gauge metal fastening applications, including HVAC ductwork, electrical enclosures, and sheet metal assemblies where a 12-24 x 1.5-inch self-drilling screw with hex washer head is specified.

Installation Notes

Install with a hex driver or nut driver sized for the hex washer head, or use a star drive bit with the included Pro-Stick design to minimize cam-out. No pilot hole is required in metal up to 1/8 inch thick. Ensure workpieces are clamped or secured before driving to prevent material shift. Follow applicable trade codes and employer safety guidelines when working with power drivers on metal substrates.
