DGMF Male Thread Stop Bolt Installations

When using a urethane washer on the stopper bolt, be careful of the forming dimension of the counterbore depth (W) for securing the stroke (S).

The dimension of the stopper bolt is set so that the head is recessed 2 mm below the mounting plate.

When using a urethane washer, the relationship between the counterbore depth (W) and the stroke (S) is (W=S+urethane washer thickness T+stopper bolt head thickness K+2].

 

 

 

 

DGMF Male Thread Stop Bolt Usage

Shaft diameters D for stopper bolts STBG and puller bolts PBTN are identical and can be combined.
When using a D20 stopper bolt, use it together with a D20 puller bolt

The stopper bolts are designed to sink 2mm from the surface of fixed installation plates listed in the right table.
Therefore, the relationship between the counterbore depth (W) and stroke (S) is W=S+(Stopper bolt’s head thickness K)+2
L=(Fixed installation plate thickness)-(Stopper bolt’s head thickness K+2)

When a runner stripper plate thickness in the following table is used, the screw length for the stopper bolt is designed to fit into the puller bolt in a length of 1.5 times longer than the screw diameter.

In this state, the stopper bolt’s thread has an 8mm part not fit into the puller bolt so that a counterbore can be created on the runner stripper plate to house a spring.

E=(Stopper bolt M diameter)X1.5+(Runner stripper thickness)
