SI® Press-In Inserts


Hexagonal – Types NFPA, NFPC

hexagonal press-in inserts NFPA, NFPC

Hexagonal inserts, types NFPA (aluminum inserts) and NFPC (stainless steel inserts) provide strong, reusable threads with no heat or ultrasonics required. The hexagonal "barbed" configuration ensures high torque-out and pullout values.

Thru Threaded – Type PPA, PPB

thru threaded press-in inserts PPA, PPB

Thru threaded, types PPA (aluminum inserts) and PPB (brass inserts) are press-fit inserts with strong, reusable threads. No heat or ultrasonics are required. The slotted insert compresses allowing easy access into the mounting hole.

Flange-Head – Type PFLA, PFLB

flange head press-in inserts PFLA, PFLB

Flange-head, types PFLA (aluminum inserts) and PFLB (brass inserts) are press-fit inserts with strong, reusable threads. No heat or ultrasonics are required. The flange-head eliminates direct contact of plastic with mating parts. The slotted insert compresses allowing access into the mounting hole.

Straight Knurl – Type PKA, PKB

straight knurl press-in inserts PKA, PKB

Straight knurl, PKA (aluminum inserts) and PKB (brass inserts) are press-fit inserts with strong, reusable threads. No heat or ultrasonics are required. The straight knurling at the top end of the insert offers higher torsional resistance. The slotted insert compresses allowing access into the mounting hole.
