The steps in our tooth blocks and locating washers work with the table holes to place the fixture right where you intend. The teeth pitch and bolt system let you create positive locking stops at set increments. The tooth blocks are designed to always provide a full range of adjustment while always maintaining two points of contact that are square with system holes. The standard range and increment we use in the “FA Series” blocks for inch spaced tables is adjustment from 0-2” in 1/8” increments.
By adjusting the hole position on our tooth washer relative to the teeth, it’s also possible to get a 1/16 to 1-15/16” range with 1/8’ increments where every increment falls on a 16th instead of an 8th.
The teeth of the block are designed to be used face down on the table which prevents
spatter from getting into the part.
The tooth block can also be used without the washer to provide the same function as a slotted “infinite adjustment” fixture.
The tooth block system brings the benefits of positive locking at set increments while still retaining the option to function as a regular slotted fixture.
