Fastening Maxx SteelBinder #12 x 1 Tan Screws with EPDM Washer

Our review of the Fastening Maxx SteelBinder #12 x 1 tan screws finds them aimed squarely at contractors and DIYers fitting metal roof and sidewall panels on pole barns and pre-engineered metal buildings. The single biggest reason to buy is their combination of a hybrid self-drilling point and a cupped head with EPDM washer, which together deliver quick penetration into multilayer steel and a reliable seal even when driven at an angle. In practice they balance corrosion resistance and pull-over strength, making them a practical choice when matching panel finish and long-term performance matter.

Key Features

• Hybrid self-drilling point: The mixed 2- and 3-point design helps the screw bite quickly and resist point walking when penetrating multilayer steel.
• Maxx self drill cupped head: The 5/16 cupped head provides strong pull-over strength and maintains a positive seal at varying drive angles.
• EPDM washer retention: The washer is captured by the head and washer face, protecting the rubber from direct UV rays and improving longevity of the seal.
• Powderful coating: A 2.5 mils powder coating with UV inhibitors resists chalking and fading so the finish continues to match panels for years.
• #12 Carbon steel construction: Sized for common metal panels, these fasteners are built for typical pre-engineered metal building applications.

Who It's For

These screws work best for builders, roofers, and owners of pole barns who need a durable fastener that threads and seals reliably in 26 gauge up to thicker panels. They are particularly useful where color match and resistance to fading are important, and where installers expect some variability in driving angle.

People who should look elsewhere include users who require specialty stainless steel fasteners for extreme coastal corrosion resistance or those needing a different head style or diameter than #12. Also, buyers who expect perfect drilling accuracy every time should be aware that a small percentage of fasteners may not drill ideally in every situation.

Pros & Cons

Pros

• Strong pull-over resistance from the 5/16 cupped head and captured EPDM washer.
• Good corrosion defense from a 2.5 mils powder coating with UV inhibitors for long-lasting finish match.
• Hybrid self-drilling point speeds installation and reduces walking on multilayer steel.

Cons

• Some customers report mixed drill accuracy, with roughly 5-10% not drilling perfectly in all cases.

Our Verdict

The Fastening Maxx SteelBinder #12 x 1 screws are a solid, value-oriented choice for metal building applications where a reliable seal, fade-resistant finish, and efficient self-drilling action matter. Contractors and owners who need good pull-over strength and long-lasting appearance will find them worthwhile, while those needing flawless drilling every time or specialty corrosion alloys may prefer alternative fasteners.

Frequently Asked Questions

Are these screws suitable for 26 gauge metal panels?
Yes, customers report they work well on 26 gauge panels, and the hybrid point is designed to penetrate common panel thicknesses.

Do the EPDM washers stay in place when driven at an angle?
Yes, the head and washer face are designed to capture the EPDM washer and protect it from direct UV exposure even when driven at an angle.

How does the coating perform over time?
The 2.5 mils powderful coating includes UV inhibitors and resists chalking and fading, helping the screws maintain a color match for years.
