ClipScrews™ Standing-Seam Roof Clip Fasteners

Our durable ClipScrews are available in QuikDrill™ metal-to-metal and QuikGrip™ metal-to-wood and UltraLo metal-to-wood configurations.

QuikDrill Metal2Metal Specs

These self-drilling screws are ideal for light- to medium-gauge metal-to-metal building applications and feature drill points designed to penetrate a wide variety of metal thicknesses. QuikDrill #2 and #3 points utilize a chisel flute that speeds up drilling time and eliminates point walking. The #10, #12 and #14 HWH are available with or without a bonded sealing washer.

 

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.

Correct: Drive fastener level to metal surface.

Incorrect: Fastener not level with metal surface.

QuikDrill Metal2Metal ClipScrews Specs
Our QuikDrill Metal2Metal ClipScrews are designed to attach standing-seam roof clips to steel purlins or frames. The special low-profile design features pancake heads and a deep thread that pulls the fastener tighter and resists pull out. As a result, you won’t get the dimpled roof panels and loose panel problems typically caused by regular profile heads that don’t fasten tight. Like all Marco ClipScrews, our QuikDrill Metal2Metal ClipScrews come standard with 8-micron electroplating for exceptional lubricity, wear resistance, and excellent durability.

QuikDrill P2M
Our P2M fasteners are ideal for plywood-to-metal applications where either a #3 or #4 point is required for a clean cut. This winged fastener reams a hole in the wood to prevent the threads from engaging as you drill. When the fastener hits metal, the wings break off and threads engage the metal for a fast application and strong hold.
