About Tightening Screws
• Use a hex socket head cap bolt for the attachment to the base.
• It is recommended to use high-tensile bolts with ISO-10.9 or more.
• Make sure to have the effective length of bolt engagement described below or more for the
tightening of a bolt and a female screw.
When female screw is on steel ĺ Thread length same as nominal diameter
When female screw is on aluminum ĺ Thread length 1.8 times longer them nominal diameter
Caution: • Pay special attention when selecting the bolt length. In case that an inappropriate
length of a bolt is applied, it may cause damage on the tapped holes or insufficiency
in attachment strength, which may result in a drop in the operation accuracy or an
unexpected accident.
• When attaching a transported object, pay attention not to apply a viscous liquid
such as glue or paint on the stainless steel sheet, or not to apply force on a spot,
which could make a dent mark. Doing so may cause an operation error of the slider
or damage on the sheet.
