Metal2Wood

QuikGrip Ultra Pro 20 Metal2Wood Specs
Our Metal2Wood fastener is designed to attach steel roofing and siding used in post-frame and residential metal roofing applications. A high-hex washer head provides driving stability, Hi-Lo threads deliver superior holding strength and the Type 17 point makes installation quick. High-quality mechanical zinc plating provides extended corrosion resistance while a bonded seal washer creates a truly Weather-Tite™ seal–even when driven at an angle.

Metal2Wood HD

QuikGrip Ultra Pro 20 Metal2Wood HD Specs
This is your heavy-duty fastener designed to withstand the stresses of demanding applications. EPDM rubber is bonded to the steel washer to prevent delaminating, forming a superior seal—even when driven at an angle. The 5/16" HWH with bonded sealing washer covers the existing hole completely, creating a watertight seal, even if stretched out by movement of the metal roof. And like our standard Metal2Wood fastener, mechanical zinc plating provides extended corrosion resistance.

LoPro™

QuikGrip LoPro Specs
LoPro provides a quality, low-profile appearance on sidewall and roofing applications installed into wood substrates. Featuring a round head with a hexalobular internal drive, LoPro is specially designed to fit a standard T-25 internal drive bit. The undercut fastener head with the EPDM rubber washer provides a secure seal even when driven at an angle. And the yellow dichromate zinc plating delivers better corrosion resistance than standard-plated fasteners.

300ss

QuikGrip 300ss Specs
Our 300ss stainless steel HWH and bonded washer provides protection in the harshest environments. With its 25° sharp point, the 300SS is an excellent choice for use in aluminum liner panel applications and can also function well for animal confinement structures. Whatever the application, the HWH design holds the EPDM rubber washer to provide a protected seal, even when driven at an angle.

Installation Tip

Always choose the appropriate fastener for the thickness and type of material to be drilled for any given application. To ensure optimum fastening performance, a 1900 to 2500 RPM screw gun rated 6 amps or more and fitted with a properly adjusted depth-locating nosepiece should be used. Sufficient pressure must be applied while screw gun is perpendicular to the working area. Overdriving fasteners can lead to leaks and other problems.

A lobe socket grips the fastener on 6 sides to prevent paint chipping which leads to rust. The nosepiece of the drill needs to be set to the correct height for proper washer installation.
