Internal Tooth Lock Washers
DIN 6797 J are internal toothed washers that can guarantee discreet locking, in particular on non-flat bearing surfaces.
The Square Head Bolt is convenient for the wrench to jam or rely on other parts to prevent rotation. It can also be used in parts to adjust the position for relatively rough structures. And it can be an ideal facility used on rough structures in order to make the machine in good condition, with high and reliable performance.
Square Washers DIN 436 - 1990
Square washers are square in shape and may be flat on both sides or flat on one side and beveled on one side. Often used with square head bolts, square washers prevent pull through and provide a larger surface area and greater hold than standard round flat washers.
