Jet jt9-jjp12-070 Knife Locking Bar Screw

Product Description

The JET jt9-jjp12-070 is a knife locking bar screw designed as a genuine replacement fastener for JET jointer and planer equipment. This screw secures the knife locking bar assembly in place, holding the cutterhead knife firmly during operation. A properly torqued and undamaged locking bar screw is critical to safe, accurate cutting performance. Woodworking shop technicians and equipment service professionals install this part during routine blade changes, preventive maintenance, or when an existing screw is stripped, damaged, or lost.

This part is intended for use in JET stationary woodworking machinery that uses a knife locking bar cutterhead system. Typical applications include bench-top and floor-model jointers and planers where the cutterhead knife is retained by a locking bar and screw arrangement. It is suited for professional shop environments as well as serious woodworking operations that depend on reliable, repeatable knife seating.
