100-Piece 12mm Grommet Kit

This practical grommet kit delivers 100 fully assembled grommet sets — each consisting of one cupronickel grommet and one washer — packaged individually in PE bags for easy access and inventory control. Also included are a hardened steel punch tool and a dedicated attaching tool, all supplied in a compact, damage-resistant plastic storage box. Grommet dimensions: ~12 mm inner diameter, ~21 mm outer diameter, ~5 mm height. The cupronickel body with galvanised coating ensures lasting resistance to corrosion and maintains visual appeal after repeated handling and outdoor exposure. Use begins with punching a clean round hole, followed by insertion and firm clinching — a repeatable process ideal for batch production or one-off repairs. Widely applied in tarpaulin reinforcement, tent fabrication, textile signage, soft luggage, leather accessories and classroom craft activities.
