Different dimensions upon demand.

For the fastening of stair treads we supply:


Hexagonal head bolts M 12 x 35 ISO 4017 (DIN 933)
Hexagonal nuts M 12 ISO 4032 (DIN 934)
Washers (2 pcs) M12 ISO 7089 (DIN 125A)


Installation


The stairtreads in accordance to DIN can be produced regarding the length with a minus tolerance and furthermore the stair construction can have tolerances. So it may be necessary to verify before srewing the treads if a washer between cheek and stairtread is needed. Thereby possible damages of the welding of the metal plank to the side plates can be avoided.
