Fasteners Plus ST Fastening Maxx SteelBinder #12 x 2 Screws - Roofing

In this review the Sealtite Maxx Steelbinder #12 x 2 Bright White screws are assessed for contractors and DIYers who need reliable fasteners for metal roofing and siding. The bottom line: these self-drilling screws are best for pre-engineered metal buildings and pole barns where long-term hold and color retention matter most. The review focuses on their hybrid self-drilling point, cupped head with EPDM washer, and the heavy powderful coating that promises fade resistance and long-term protection.

Key Features

• Hybrid Self-Drilling Point: The combination 2- and 3-point design makes penetration through multilayer steel quicker and reduces point walking for neater installs.
• Maxx Self Drill Cupped Head: The 5/16 cupped HWH head seals at angle and protects the washer so you get a positive seal even on imperfect drives.
• #12 Carbon Steel Construction: Sized to attach metal roof and sidewall panels used in pre-engineered metal building applications for secure long-term retention.
• EPDM Washer Capture: The head and washer face hold the EPDM washer even when driven at an angle, maximizing pull over strength and sealing performance.
• Powderful Corrosion Defense: A 2.5 mils powder coating with UV inhibitors resists chalking and fading so the finish stays matched to panels for years.

Who It's For

These screws suit contractors, metal building erectors, and experienced DIYers working on pole barns, agricultural buildings, and pre-engineered metal structures who need dependable self-drilling fasteners with good corrosion and UV resistance.

They are less appropriate for thin decorative metal trim where a more delicate screw or matching head style is required, and users who need perfect drill success on every single fastener should be aware that a minority of pieces may show drill accuracy issues.

Pros & Cons

Pros

• Strong self-drilling point reduces walking and speeds installation on thicker steel layers.
• EPDM washer design and cupped head provide consistent sealing and pull-over strength at angles.
• Durable powderful coating resists fading and helps maintain building appearance long term.

Cons

• Some customers report about 10% may not drill properly, so occasional rejects can slow an install.
