Value Collection MS-1153 Indexable Insert Cap Screw T7 Torx

Product Description

The VALUE COLLECTION MS-1153 is a cap screw engineered for securing indexable cutting inserts in toolholders used in metal machining and turning applications. Featuring a T7 Torx drive and M2.5 x 0.45 thread, this screw is designed to provide consistent clamping force on carbide and cermet inserts without stripping under the repeated installation and removal cycles common in production environments. The overall length is 0.256 inches and the head diameter measures 0.136 inches. This screw conforms to industry standard number MS-1153 and is sold individually with a minimum order quantity of 10 units.

This cap screw is intended for use in CNC turning, milling, and boring toolholders that accept indexable inserts with a center-hole clamping design. It is a standard consumable item in machine shops, toolrooms, and production facilities where indexable tooling is routinely serviced. Machinists and tooling technicians handling high-volume insert changes will find this screw dimensionally consistent with MS-1153 specification requirements.

Compatibility

Designed as an MS-1153 specification cap screw for indexable insert toolholders that use a T7 Torx center-clamp screw with M2.5 x 0.45 thread. Verify toolholder manufacturer specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician using a calibrated T7 Torx driver or key. Always clean the threaded bore in the toolholder before installing a replacement screw to prevent cross-threading. Do not over-torque; follow the toolholder manufacturer's recommended torque specification for the insert clamping screw. Ensure the machine spindle is fully stopped and locked out before servicing any indexable tooling.
