Keensert and Keysert Key locking Inserts provide high strength and reliability and are designed to provide high resistance to rotation and pull-out loads.After installation into the tapped hole, the locking keys on each Keensert are driven down through the threads of the parent material, locking the insert firmly and permanently in place.

Features:

• Easy instll,high strength,high cycle life.

• Positive mechanical lock eliminates wind out in service

• Signicantly increase torque-down and load capability in weaker maerials

• No special taps required

• No tangs to break off and remove

Applications :

• Trucks, RVs

• Machinery, Small Engines

• Molds, Tool and Die

• MRO Tasks

Material: In Carbon Steel - C1215 or equivalent

In Stainless Steel - 303 or equivalent

Keys - 302 CRES or equivalent

Finish: Carbon Steel - Zinc Phosphate

Stainless Steel - Passivated

Tolerances: ±.010 inch or ±.25 mm unless specified otherwise.

Dimensions: Are in inches except metric inserts are in millimeters.

Metric/Inch inserts have a metric internal thread while

all other dimensions are in inches.

Keys: Inserts with an internal thread size of 5/16 or M7 and larger have

4 locking keys,smaller sizes have 2 locking keys.

Tap Drill Hole Tolerance: Inch - .234 to .500 = +.004/-.001

Inch - Over .500 = +.005/-.001

Metric - 6.90 to 10.80 = +.100/-.025

Metric - Over 12.80 = +.130/-.025
