Cost-effective and efficient method of attaching metal to wood or other soft material without through holes.

T-Lok® rivets are an ideal replacement for wood screws or self-tapping screws. The T-Lok® rivet does not break through the back substrate, yet has a large rivet-tail bearing area inside the material, giving this rivet an excellent pull-out force.

Often used for garage door and furniture assembly applications, the T-Lok® 'peel-type' tail formation makes it ideal for joining metal to wood, board, or low-density plastic.
