KEENSERT STYLE (MS51830-31-32) INSERTS: INCH & METRIC

 

These universally popular inserts provide strong, permanent metal threads in virtually any material: ferrous or non-ferrous. Standard insert material is type 303 stainless steel.

 

Positive mechanical lock against rotation  

  • Installed with standard taps and drills
  • Available from stock in many sizes and types

KEES are driven down into the tapped threads of the parent material during installation to securely lock the insert against rotation. Featuring an exclusive external trhread design, KEENSERTS provide maximum pull-out strength with a minimum outside diameter.

Internal thread lock feature available.

Inserts with this feature are designed to securely lock a bolt when it is entered into the insert in only a few turns. The locking torque values are consistent and well within the range established by MIL-I-45914A. Even after repeated installations and removals of the bolt, the lock maintains sufficient locking torque to prevent the bolt from vibrating out.

These one-piece insets are supplied with KEES pre-assembled into dove-tailed slots at the factory to eliminate the problems of selecting, stocking and assembling separate parts. The prepositioned KEES automatically set the insert at the proper depth below the surface of the parent material.

Unlike conventional inserts, there is no need to maintain critical depth tolerances..no chance of inadequate locking or deformation of internal threads due to miscalculations of depth.

  • DRILL with a standard drill-PLEASE NOTE: DRILL TOLERANCES LISTED BELOW!
  • INSTALLATION TAP-DRILL HOLE TOLERANCE (dimension in inches)

.120" to .233" : +.002"/-.001"

.234" to .500" : +.004"/-.001"

Above 500" : +.005"/-.001"

  • COUNTERSINK with a STANDARD countersink
  • TAP with a STANDARD Unified Thread Series tap

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Screw in insert with fingers or installation tool. Insert is designed to stop at the correct depth below the surface of the casting. Using the intallation tool, drive in the KEES. The tool may be used with a hammer or held in an arbor press. The correct insert tool is tabulated with each type of insert in our catalog.

  • For Miniature Series inserts, screw the insert onto the threaded mandrel and turn the insert into the tapped hole.
  • When the tool handle is depressed, a special spring loaded mecanism within the tool will drive the KEES into the parent material
  • The replacement of inserts is accomplished without reworking the parent material, and the same size insert is used in the original hole.

METRIC SIZE INSERTS

NOTES on Metric Inserts:

        These inserts are used in the same way and have the same design features as the MS style inserts detailed in the proceeding pages. Since there are no military or aerospace part numbers or specifications governing them, parts are typically referenced by AFS (Keensert) part number. Parts supplied may be either AFS or ACME manufacture.
