ST® Grommet

Grommet consists of 316 Stainless Steel machine screw, 304 Stainless Steel bonded washer, & internally threaded rubber sleeve with preassembled nut.

As the fastener is tightened, the rubber sleeve expands to provide a gasketing effect on the bottom side of the pre-drilled hole.

Applications include fastening fiberglass sheets together or other dissimilar materials that are prone to extensive expansion & contraction due to temperature changes.

316 Series Stainless Steel bonded washer is available as an option.
