Overview
The SelfSert-SBI is the insert-in-insert variant of the self-tapping family: a self-tapping external body carries a replaceable internal insert, so the working thread can be renewed without removing the body from the parent material. This protects the boss from repeated installation damage on joints that are serviced many times. This listing: thread M5, standard ISO metric thread, material Case-hardened steel, finish Blue zinc passivated, features Hex-socket self-tapping.
What sets this listing apart: Thread Diameter M5 (series runs M4 to M12).
Advantages
Only the inner insert is replaced, which is a smaller, cheaper part than a full insert and can be swapped without re-tapping the housing.
Self-tapping external thread keeps the one-step installation benefit for the initial assembly.
Internal thread can be renewed to the original size, so the mating screw does not have to change through the equipment life.
The outer body stays in the parent material permanently, so repeated service cycles do not wear the boss hole — the usual cause of insert loosening after several repairs.
Applications
Equipment serviced at fixed intervals, rental and lease fleets where threads are opened repeatedly, test fixtures rebuilt for each programme, and any joint where the housing is expensive relative to the fastener.
Specify the number of expected service cycles: beyond a certain point the inner insert, not the outer body, becomes the consumable, and spare inner inserts should be stocked accordingly.
