Acorn International Wood Screws, 2-1/2 in, #9, Galvanized Steel, Hex Washer Head, 250/Bag

They drive clean and hold tight, so your roofing and siding work settles in with less fuss.

A solid choice when you want a steady bite and a cleaner finish.

Product Overview:

If you work with metal to wood fasteners, you know the little things matter fast. This Acorn International screw gives you a sharp, self piercing start, then keeps moving with twin lead type 17 point and hi lo threads. It is built from heat treated C1022 steel, case hardened for roofing and siding jobs, and the EPDM washer helps the head settle down with a snug seal. You get a silver finish, a 1/4 inch across flat high hat hex washer head, and a bag of 250 pieces, which feels about right when the job runs long. Picture a cleaner install, less wobble, and that quiet, reassuring pull when the screw seats proper.

Key Features:

• Self piercing point: The twin lead type 17 point gets you started quicker, so the screw bites without a lot of wrestling.
• Secure sealing washer: The assembled EPDM washer conforms to the surface, helping you get a tight, long lasting seal that feels right.
• Built for tough jobs: Heat treated C1022 steel and case hardening give it the grit you want for roofing and siding work.
• Easy driving head: The 1/4 inch across flat high hat hex washer head sits steady, so your driver stays planted instead of skating around.
• Resists pull out: Hi lo threads help the screw hold its ground once it is set, which brings a bit of peace of mind.
• Finish that stands up: The dacro coating is salt spray tested for 1,000 hours, and the silver powder coat keeps the look neat and plainspoken.
