#10 x 1-1/2 in ZXL Woodbinder Metal Roofing Screws - Durable Choice

In this review the Fasteners Plus ST Fastening #10 x 1-1/2 in ZXL Woodbinder screws are examined for roofers, contractors and serious DIYers who need fasteners that resist corrosion and drive consistently. The single biggest reason to buy is long-term durability: the screws combine a 2.5 mil powder coating over zinc plating with a ZAMAC molded head and an EPDM washer to shield the joint from weather and UV, which makes them a reliable choice for metal-to-wood roofing work.

Key Features

• Coated Screws: The 2.5 mil computer controlled powder coat over zinc plating and chromate sealer provides strong resistance to UV rays and chemical breakdown for prolonged outdoor exposure.
• ZXL No Rust Head: The 5/16 in cupped hex washer head is molded from ZAMAC zinc-aluminum alloy and encapsulates the EPDM washer to reduce leakage and maintain a secure seal.
• KS Lo-Root Thread Design: The thread transitions from fine to coarse with a low root profile to improve pullout strength in wood compared with traditional thread forms.
• Micro-Bit Point: The drill-point design penetrates metal panels cleanly and removes the need to pre-punch, simplifying installation on ridge caps and trim.
• Pack Quantity: The screws are sold in a bulk pack of 250, suitable for larger roofing runs or multiple projects without frequent reordering.

Who It's For

These screws are aimed at professional roofers and experienced DIYers working on metal-to-wood installations who value corrosion resistance and a reliable washer seal. The combination of powder coat, zinc plating and a molded EPDM washer addresses outdoor exposure and helps extend the life of the fastened connection.

Those who should look elsewhere include users needing very short or very long lengths than 1-1/2 in, or those on strict budgets who prefer the cheapest fasteners for one-off interior projects where advanced coatings and a molded head are unnecessary.

Pros & Cons

Pros

• Durable protective finish that resists UV and chemical breakdown for outdoor use.
• Molded ZAMAC head encapsulating an EPDM washer gives a neat seal and consistent fit.
• Micro-bit drill point reduces pre-drilling and handles multiple thin steel layers well.

Cons

• Higher unit cost noted by customers, which may be a concern for tight budgets.
