Metal to Metal #12 x 1-1/2ft Bright White Screws with EPDM Washer

Our review of these metal-to-metal #12 x 1-1/2' bright white screws finds them aimed squarely at contractors and builders who need a durable, color-matched fastener for metal roofing and siding panels. The single biggest reason to buy is the combination of a hybrid self-drilling point and a cupped head with EPDM washer, which together deliver reliable penetration into thin steel and a strong weather seal that helps protect the roof edge and preserve aesthetics over time. This is a practical choice when longevity and a neat finish matter more than bargain pricing.

Key Features

• Hybrid self-drilling point: The 2- and 3-point design lets the screw penetrate multilayer steel cleanly, reducing the chance of walking and speeding up installation.
• Maxx self drill cupped head: The 5/16 cupped head and HWH design provide a positive seal at an angle and protect the washer from direct UV exposure.
• #12 carbon steel construction: Sized and shaped specifically for attaching metal roof and sidewall panels used in pre-engineered metal building work.
• EPDM washer retention: The head and washer face capture the EPDM even when driven at an angle to maximize pull-over strength and maintain a tight seal.
• Powderful corrosion defense: A 2.5 mils powder coating with UV inhibitors resists chalking and fading so the finish matches panels for years.

Who It's For

These screws are best for professional installers, farm and pole-barn owners, and anyone working on pre-engineered metal buildings who needs a reliable, weather-resistant fastener that also maintains a color-matched finish. The combination of self-drilling geometry and EPDM washer makes them suited to standard metal panel thicknesses and common roofing and siding applications.

Those who need screws for thicker structural steel, unusual panel profiles, or highly precision drilling in all conditions should consider specialized fasteners or test a sample first, since customers reported a small percentage with drilling issues under some conditions.

Pros & Cons

Pros

• Durable powder coating with UV inhibitors preserves the finish and resists fading over time.
• Hybrid self-drilling point reduces walking and allows faster installation through multilayers.
• EPDM washer and cupped head design provide a strong, positive seal even when driven at an angle.

Cons

• Some users reported mixed drill accuracy, with roughly one in ten not drilling properly under certain conditions, so pre-testing is recommended.

Our Verdict

These screws are a solid value for roofing and siding work on pole barns and pre-engineered metal buildings, offering a balance of ease of installation, sealing performance, and long-lasting finish. Professionals who need consistent results will appreciate the hybrid drill point and EPDM sealing, but it is wise to test a small sample for drill accuracy on the exact panel gauge and fastener gun being used.

Frequently Asked Questions

Are these screws suitable for 26 gauge panels?
Yes, customers reported they work well on 26 gauge panels, though testing a sample on your panel profile is recommended.

Will the powder coating resist fading?
Yes, the 2.5 mils Powderful coating includes UV inhibitors to resist chalking and color fade over time.

Do the washers stay seated when driven at an angle?
Yes, the head and washer face are designed to capture the EPDM washer and maximize pull-over strength even when the fastener is driven at an angle.
