#12 x 1 Metal Roofing Screws Pack of 250 - Self Drilling Metal

In this review of the #12 x 1 Metal Roofing Screws Pack of 250, the bottom line is simple: these are a practical choice for builders and DIYers who need a reliable fastener for metal roof and sidewall panels. The reviewer found the single biggest reason to buy is their combination of a true self drilling point and a cupped head with EPDM rubber washer that seals well even when driven at an angle, making them especially useful on pre-engineered metal buildings and pole barns where speed and weather resistance matter.

Key Features

• Self drilling: The fastener easily penetrates steel up to 0.210in thickness, saving time and reducing the need for pilot holes.
• Powder coated finish: A durable 2.5 mil powder coat with UV inhibitor helps keep the finish from chalking or fading over time.
• EPDM rubber washer: The cupped head encapsulates the washer to maintain a secure weather seal even when screws are not perfectly perpendicular.
• Deep penetration: The drilling tip reduces "point walking" for cleaner starts and more consistent installation through thin gauge metal panels.
• Color matching: Available in common high-volume panel paint colors to help screws blend with metal roofing and siding.

Who It's For

The screws are aimed at contractors, metal building erectors and homeowners working on pole barns, agricultural buildings, or metal-clad storage structures who need a bulk supply of reliable fasteners. Their self tapping capability and sealing washer make them a practical choice when installing 26 gauge and similar panels.

Those who need fasteners for very thick structural steel, specialty coatings, or precision-drilling applications should look elsewhere, as these are optimized for typical metal panel attachment rather than heavy structural or specialty metalwork.

Pros & Cons

Pros

• Good overall durability and finish thanks to a 2.5 mil powder coating with UV inhibitor.
• Secure weather sealing provided by the cupped head and EPDM rubber washer.
• Consistent penetration into sheet steel up to 0.210in without frequent pilot drilling.

Cons

• Some users report a small percentage of screws that do not drill correctly, so occasional rejects may occur.
