AP bolts are modern design anchors with load capacity of up to 300 kN and a nut locking system (shearpin.
APP; APG; APB anchor rod is made from a reinforcing bar of 21.70 mm in diameter according to ZN-95/AP-1; ZN-02/AP-6 made of the following type of steel:

M24 nut is connected with the rod by means of a "SPIROL" ø3 or ø6 pin.
Spherical washer makes it possible to fix the anchor at 18°angle.
The anchor can be used with a square, round washers or square washer with an eyelet made of 8 or 10 mm plate.

Put resin cartridges in the drill hole. Insert the anchor and rotate while pushing causing the resin to mix. During mixing, the nut does not turn as it is joined with the rod by means of a ø3 or ø6 pin.
Once the resin has set, the pin is sheared by turning the nut. Apply torque of at least 250 Nm to screw on the M24 nut in order to tension the anchor to the desired pre stress (initial tension) of minimum 30 kN.
APP, APG, APB adhesive anchors have a Certificate issued by Central Mining Institute in Katowice allowing the product to bear the safety mark No. B/1160/IV/2014.
