ST Fastening #14 x 7/8ft Metal Roofing Stitch Screws - Pack of 250

In this review of the ST Fastening #14 x 7/8' Maxx Steelbinder stitch screws, the bottom line is simple: these are practical, heavy-duty fasteners for metal-to-metal roofing where a reliable seal and consistent penetration matter. The reviewer found them best for pole barns, metal roof and wall panels, and other pre-engineered steel buildings because the self-drilling point and cupped EPDM washer combine to deliver a secure attachment and weatherproof seal in most common panel thicknesses.

Key Features

• Self drilling: The fastener drills through metal up to 0.210' thick, eliminating the need for pre-drilling and speeding installation on roof and wall panels.
• Powder coating: A tough 2.5 mils of powder coat resists chalking and fading over time thanks to UV inhibitor in the colored finishes.
• EPDM rubber washer: The cupped head with embedded washer provides a secure, weather-tight seal even when the screw is driven at a slight angle.
• Deep penetration: The point design reduces "point walking" and ensures consistent engagement through the substrate for a firm hold.
• Color match options: Available to match common metal panel paint colors so exposed fasteners blend with the roof or wall finish.

Who It's For

These stitch screws are aimed at contractors, metal building erectors, and handy homeowners installing or repairing pole barns, sheds, and other pre-engineered metal structures who need a durable metal-to-metal fastener that can drill and seal in one step. The combination of a self-drilling point and EPDM washer makes them suitable for through-fastening applications on 26 gauge and thicker panels up to 0.210'.

DIYers who need occasional roofing screws will find value here, but those requiring specialty coated fasteners for unusually corrosive coastal environments or non-standard panel thicknesses should verify compatibility or consider a different fastener system designed for those extremes.

Pros & Cons

Pros

• Good overall build quality and strength for metal-to-metal roofing applications.
• Powder coating with UV inhibitor helps maintain finish and reduce chalking over time.
• EPDM washer provides a reliable seal even when driven at an angle, reducing leaks.
• Self-drilling point penetrates common panel thicknesses without pre-drilling, saving time.

Cons

• Some customers reported mixed drill-end performance, so a quality screw gun and correct technique may be needed to avoid occasional point damage.
• Not explicitly specified for extreme corrosive exposures, so coastal use should be confirmed.
