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.
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.
