Good To Know

Q: What is the purpose of step keys instead of standard straight keys? A: Step keys allow a vise with a larger keyway width to align with a machine table that has smaller T-slots, bridging different sizing standards securely. This avoids having to modify the vise or table.

Q: How are these keys secured to the vise? A: These keys attach to the bottom of the vise base using socket head cap screws, locking them into the vise keyway so they remain aligned during repositioning. Always clean the slot thoroughly before mounting.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
