Allied 75020-IP20-1 Indexable Mounting Screw M5 X 0.80 Apx

Product Description

The ALLIED MACHINE AND ENGINEERING 75020-IP20-1 is a Torx Plus drive mounting screw designed for indexable drilling toolholders in the APX series. This M5 x 0.80 threaded fastener secures indexable drill heads to compatible toolholders and is driven with an 8IP-20 key driver. Weighing 0.02 pounds, it is a precision hardware component intended for use by machinists, toolroom technicians, and CNC setup personnel maintaining or assembling indexable drilling systems. The screw is sold individually per package with a minimum order quantity of 4 units.

This mounting screw is used in metal cutting and machining environments where indexable drill heads are mounted to APX series toolholders. It is suited for production drilling operations in both job shop and high-volume manufacturing settings. The Torx Plus drive geometry provides improved torque transfer during installation, reducing driver slip and fastener damage during routine insert and head changes. Compatible toolholder models span multiple shank styles and diameter ranges within the APX series lineup.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with indexable tooling systems. Power down and lock out the machine spindle before replacing or torquing mounting screws. Use only the specified 8IP-20 Torx Plus key driver to avoid fastener damage. Follow the toolholder manufacturer torque guidelines published in the applicable product documentation — do not estimate torque by feel on indexable mounting hardware.
