M6 Countersunk Timber Insert, 316 Stainless Steel - CTIA4M6L
Available
This 316 stainless steel countersunk timber insert is a threaded insert with an external timber thread and a countersunk flange. It is screwed into timber to give a machine thread (M6) for a bolt or screw. A left hand thread version is also listed.
This listing is a single size: M6. Each variant is supplied in packs of 10.
A4 (316) stainless steel contains molybdenum (about 2 to 3 per cent), which improves its resistance to chlorides. It is the grade normally chosen for coastal, pool, marine and food-processing settings, and it costs more than A2 (304). Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.
Use stainless washers and nuts with stainless fasteners, so the whole joint is made of the same material.
