Stewart Fastener J1212BHTZ Hex Head Self-drilling Screws 100pk

Product Description

The STEWART FASTENER J1212BHTZ is a hex head self-drilling screw, commonly called a Tek screw, sized 12-14 x 3/4 inch. These screws are designed to drill their own pilot hole and tap threads in a single pass, eliminating the need for pre-drilling in many metal-to-metal and metal-to-framing applications. Sold in a jar of 100, this package is suited for trade professionals who need reliable fasteners in quantity on the job site. The hex head drive style allows for quick installation with a standard nut driver or hex bit driver.

Self-drilling Tek screws in this size are commonly used in HVAC duct fabrication, sheet metal work, metal framing, and light structural applications. The 12-14 thread size and 3/4 inch length make them well suited for attaching thin-gauge sheet metal panels, ductwork sections, and metal track or stud assemblies. HVAC installers, sheet metal workers, and general contractors frequently use this fastener type in both residential and light commercial projects.

Compatibility

Designed as a standard Tek-style self-drilling screw for use in sheet metal and light metal framing applications typical to HVAC duct work, metal stud framing, and similar trade installations.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or metal framing crews using a hex bit driver or nut driver attachment on a power drill or screw gun. Verify that the material gauge is within the rated drilling capacity of the screw point before driving. Do not overdrive hex head screws, as this can strip threads or distort the base material. Follow applicable building codes and manufacturer fastening schedules for structural or load-bearing connections.
