Removable Drill Bushings for Thin Metal
Unlike most bushings, these won’t buckle the material or distort the hole when installed in thin-gauge aluminum and steel plates. Insert them into a drilled hole and twist the lock ring to secure. Reusable and easy to replace, they are held in place by a lock ring (sold separately).
