Threaded Inserts

More Strength. Less Wear.

Feature permanent, wear-resistant internal threads to anchor fasteners in wood, plastic, metal, or composites. Groov-Pin’s threaded inserts strengthen assemblies and increase load-bearing capacity.

Grooved Pins

Superior Holding. Shock Resistant.

Used in the automotive and aerospace industries, each cylindrical pin features three longitudinal grooves that precisely expand the pin's original diameter. This creates a superior spring mechanism and holding power.
