AChrislynn blank inserts are designed to cover unused holes and then remove when the assembly is ready for expansion. These solid inserts are threaded on the outside with wedges (keys) attached to the top of the insert. The inserts are screwed into the part and the wedges are then driven down into the tapped threads for keeping the insert from turning in either direction. They can be used in situations where a nonstandard size combination is needed. Choose from a huge variety of Chrislynn blank inserts, available in carbon steel and 303 stainless steel variants, on Raptor Supplies.
The helical insert length should be equal to the desired fastener diameter. Users may choose longer inserts than required for increased strength and holding power. The exact insert length may also vary based on the base material. Hard materials like steel do not need long inserts, whereas soft materials like aluminium require a longer insert.
Yes, key locking inserts or rock solid inserts can be removed by bending the locking keys out of the material and using a winding tool to remove the insert out of the base material in the direction opposite to that used during installation.
Locking rock solid inserts have locking keys swaged in the groove for forming internal thread lock and preventing rotation of the inserts.
