Japanese Yamashina Rolls out SPILEAD Self-tapping Screw

     Tailored to fasten thin plates, SPILEAD Self-tapping Screw gains great disparity in torque by low fastening torque and and high rupture strength. This disparity ensures secure screw fastening and make SPILEAD suitable for thin plates in 0.1T-0.2T thickness, variable bottom holes and screwdrivers with inconsistent torque. Its front end is a triple-thread design to prevent inclined screw insertion and inclined screw fastening, improving operability. A M4×6 SPILEAD screw, for instance, fastens up in just one and a half turns, reducing fastening time. Furthermore, it is short in length to avoid the threaded portion coming up from inside the fastened object after the screw is fastened.
