Midwest Fasteners Zinc Plated Steel Hex Bonded Washer Head Self-Drilling Screws

Midwest Fasteners Zinc Plated Steel Hex Bonded Washer Head Self-Drilling Screws

Midwest Fasteners Zinc Plated Steel Hex Bonded Washer Head Self-Drilling Screws are built for fast, one-step fastening into metal without pre-drilling. Constructed from zinc plated steel with a silver finish, these screws feature a hex connection and a bonded washer head configuration that seats a sealing washer directly under the head for a tight, weather-resistant hold. The self-drilling point cuts its own pilot hole on contact, saving time on repetitive fastening jobs across metal roofing, siding, and light-gauge framing work. This family is available in a full range of screw sizes, including #12-14 x 1", #12-14 x 1-1/2", #14-14 x 1", #14-14 x 1-1/2", and #14-14 x 3/4", so contractors can match the exact length and thread diameter to the application while keeping the same head style, drive, material, and finish across the job.
