Seco 00057656 Lock Screw T6 Torx 1-72 Thread Boring Bar

Product Description

The SECO 00057656 is a lock screw designed for indexable tooling systems, specifically used to secure cutting inserts and clamps in boring bar applications. The screw uses a T6 Torx drive and is threaded at 1-72, with an overall length of 0.556 inches and a head diameter of 0.11 inches. At 0.02 pounds, it is a precision fastener that meets Industry Standard Number CS-115. Installation is performed by tooling technicians and machinists during insert indexing or replacement on indexable boring bars.

This lock screw is suited for use in metal cutting and machining environments where indexable boring bars require secure, repeatable insert clamping. It is compatible with clamp-style insert retention systems on boring bars. The T6 Torx drive provides positive engagement and reduces the risk of fastener damage during high-cycle insert changes. Sold individually, with a minimum order quantity of 10 units per order.

Compatibility

Designed for use with clamp-style indexable boring bar tooling systems requiring a 1-72 threaded T6 Torx lock screw per Industry Standard CS-115.

Installation Notes

Installation is performed by machinists or tooling technicians during routine insert indexing or replacement. Use a calibrated T6 Torx driver to seat the screw properly without over-torquing. Ensure the boring bar is fully removed from the machine spindle and the machine is powered down before servicing the insert and clamp assembly. Inspect the threaded bore in the tool body for wear or damage before installing a new lock screw.
