Slotted wood insert with reservoir
Slotted wood screw-in insert with chip reservoir – DIN 7965 Type A solution for professional wood fastening
What is a slotted wood insert with chip reservoir
The slotted wood screw-in insert with chip reservoir is a self-tapping metal threaded insert, DIN 7965 Type A equivalent, designed to create a reusable internal metric thread (M3–M20) in softwood, MDF, particle board, soft plastics and lead. This slotted insert nut with chip reservoir features an unthreaded internal section that collects chips during installation, ensuring clean assembly, higher reliability and consistent results in industrial and series production environments.
Description
