Press-In, Expansion, or Self-Tapping
While not as commonly used, we offer a variety of inserts that are installed via simple press-in methods. Several of these designs are expansion-style inserts, and one is self-tapping for use with materials that have low core strength.
FIN-LOK®
A press-in insert, which can be easily installed into most thermoplastic materials. It features a combination of sharp fins and straight knurls. Unlike the Press-Lok™ range, this insert has a free running thread.
Advantages
- Easy press-in insertion
- High pull-out performance in most thermoplastics
- Self-aligning – assists installation
PRESS-LOK©
Offers ease of installation without the typical high screw installation torque and its plain and knurled vanes offer the levels of pull-out and torque resistance usually expected only of heat-installed inserts.
Advantages
- Degree of self locking action on screw
- High pull-out and torque performance
- Easy press-in insertion
- Suitable for most thermoplastics
BANC-LOK®
A press-in expansion insert that is ideal for use in hard thermosetting plastics. Due to their diamond knurl pattern, BANK-LOK® inserts give minimum penetration of the sides of the hole without sacrificing performance.
Advantages
- Easy press-in insertion
- Self locking action on the screw – ideal where vibration is present
- Suitable for most thermosetting plastics
SPIRO®
Designed to cope with the difficulties presented by hard brittle thermoset materials. The sharp precision knurl pattern cuts into these materials reducing radial stresses and allowing thinner boss walls than many other inserts.
Advantages
- Easy press-in insertion
- High torque resistance
- Low bursting stress allows the use of thinner wall bosses – reducing the risk of sink marks
- Self-aligning – assists installation
SCREW-SERT®
A self-tapping insert suitable for installation into a wide range of thermoplastic and thermosetting plastic materials. They are particularly suitable for applications involving high jack-out loading and materials with low core strengths.
Advantages
- High pull-out resistance
- Ideal where jack-out loading is unavoidable
- Can carry high loads in weak plastics
