No. Embedding performance varies widely across FRP material compositions. The guide includes indicative SMC values, but application‑specific testing is required for final validation.

Flush → thin sections, low profile. Inset → stronger engagement, moderate thickness. Socket → thick sections, full encapsulation.

Yes – by using a pocket of at least 3 mm thickness that supports good material flow.

Flush/inset: typically ≥ 3 mm. Socket: overall fastener length + 1 mm. (e.g. 12.2 mm for M4–M8 closed blind collar products.)

We do not recommend this. High moulding pressures can force resin into the thread. Use customised closed blind collar products instead.

No. Torque-out values reflect rotational failure of the embedded fastener and do not represent the safe tightening torque for installing a nut or screw. Tightening torque must be determined separately based on the specific joint design.

Yes – but for sighted (screws pass through) installations, we recommend contacting us first. These cases often require special considerations for configuration geometry, laminate consolidation, and ingress sealing.

Reinforced pockets generally offer better load distribution and mechanical performance, especially for pull-out and shear. Unreinforced pockets are acceptable where loads are modest or local reinforcement would be complex to implement.

Compare the laminate thickness at the fixing interface with the fastener’s L1 (shoulder/flange) and T (Head) values. Flush installations require the laminate thickness to match L1. Inset installations require thickness > L1 + T.

Flush works for thin laminates. Inset generally offers higher strength where laminate thickness allows. Pocketed is useful when reinforcement continuity is required. Through configurations suit applications needing a balance of maximised embedment strength with minimum reinforcement/preform disruption.
