Neoprene Washers are a Great Way to Create a Tight Seal When Used with Self-Drilling or Self-Piercing Screws.

Fastener SuperStore carries Self-Drilling Screws with attached neoprene washers in steel with a zinc finish and in 18-8 stainless steel.

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.

We also offer self-piercing screws with neoprene washers, as well as stand-alone neoprene washers in galvanized or stainless steel.
