Overview
The SelfSert-SBE adds a sealing or locking feature to the self-tapping insert form, so the installed insert both provides a serviceable thread and closes the hole against ingress. It is used where a boss must remain watertight or where a screw could otherwise back out of a self-tapping joint. This listing: thread M5, standard ISO metric thread, material Case-hardened steel, finish Blue zinc passivated, features Self-tapping with lead-in.
What sets this listing apart: Thread Diameter M5 — the smallest size in the series (series runs M5 to M16).
Advantages
The self-tapping external thread seals against the parent material along the full engagement length, so leakage paths around the insert are closed rather than left to a face seal.
Retains the one-step installation of the SelfSert family, so the sealing feature adds no station to the line.
Serviceable internal thread means the joint can be opened and reclosed without destroying the seal.
Combines thread reinforcement and sealing in one part, removing a separate O-ring or sealant step from the assembly.
Applications
Outdoor equipment housings, automotive underbody modules, pump and valve bodies, and any die-cast enclosure that must meet an ingress protection rating after the cover is opened for service.
Sealing performance depends on the parent material being sound around the boss: porosity in a die casting will leak through the wall regardless of the insert. Verify the housing passes a leak test after insert installation, not before.
