Self Drilling Screws With Neoprene Sealing Washers
October 23, 2020
Neoprene Washers are a Great Way to Create a Tight Seal When Used with Self-Drilling or Self-Piercing Screws.
Below the hex heads of these screws is a thin, conical & circular washer bonded to a similarly shaped rubber-like washer made of neoprene. The rubber section has a slightly smaller inner and outer diameter, which allows it to create a tight seal when fastened to other metal materials.
Commonly used on metal roofs, the connected washer provides better load bearing potential than standard flat washers; resists loosening caused by vibrations; and prevents leakage.
