CHEM STUD M16 DR 18MM C/W NUT&WAS

M16 x 190mm Chemical Stud, 18mm drill bit.  

Comes with nut and washer.  

After drilling and cleaning the hole, the capsule is inserted into the hole and the anchor chemical stud is driven with a rotatinghammering action. This breaks the capsule and mixes the contents. The resulting chemical reaction creates a durable expansion pressure free bond between the anchor chemical stud, the reacted resin, and the concrete.
