The pull-out strength is about 1.5 times that of regular screws! Recommended for hard materials like concrete.
The "trapezoidal screw" is a product that can dramatically improve the pull-out strength when fixing products to hard materials such as concrete. By making the screw thread trapezoidal, the apex of the thread becomes flat, which prevents it from cutting through the resin plug and allows for greater expansion. Furthermore, the increased contact area between the screw and the resin plug enhances the pull-out strength by approximately 1.5 times compared to standard screws (tapping screws). 【Features】 ■ It does not cut through the resin plug, allowing for greater expansion. ■ The larger contact area between the screw and the resin plug allows for even stronger retention. *For more details, please refer to the PDF document or feel free to contact us.
