Tool-flo 9HSF30 Indexable Cap Screw T10 Torx 5-40

Product Description

The TOOL-FLO 9HSF30 is a flat-head cap screw designed to secure indexable inserts in grooving and threading toolholders. It uses a T10 Torx drive and a 5-40 inch thread, with an overall length of 0.375 inches. The flat-head profile seats flush against the insert, keeping the cutting edge properly positioned under machining loads. This hardware is installed by machinists and tool crib technicians during insert changes on CNC lathes and turning centers running grooving or threading operations.

This cap screw is intended for use with grooving and threading toolholder assemblies that accept LPGC-series indexable inserts. It is a direct replacement screw for toolholder styles in the LFL and LFR families, specifically LFL 625-32, LFL 750-32, LFR 100-32, LFR 625-32, and LFR 750-32. Compatible inserts include LPGC 32 NT 12P INT RH, LPGC 32 NT 8P STUB INT, LPGC 32 NV INT RH, LPGC 32-NT 10P INT RH, LPGC 32-NT 8P INT RH, and LPGC 32-NV INT LH. This screw suits high-volume production environments where fast, reliable insert indexing is required.

Compatibility

Compatible toolholder styles: LFL 625-32, LFL 750-32, LFR 100-32, LFR 625-32, and LFR 750-32. Compatible inserts: LPGC 32 NT 12P INT RH, LPGC 32 NT 8P STUB INT, LPGC 32 NV INT RH, LPGC 32-NT 10P INT RH, LPGC 32-NT 8P INT RH, and LPGC 32-NV INT LH.

Installation Notes

Install and remove using a T10 Torx driver or bit. Power down and lock out the machine spindle before servicing any toolholder or changing inserts. Tighten the screw to seat the insert fully in the pocket without applying excessive force that could strip the thread or fracture the insert. Inspect the screw threads and seating surface for wear or damage each time an insert is indexed.
