Product Description

The VALUE COLLECTION 8-815-P805 is a shell mill arbor screw designed to secure shell mill cutters to milling arbors in machining and metalworking applications. This fastener features a 1/4-28 thread size and is compatible with a 1/2 inch pilot diameter arbor. It provides the clamping force needed to keep shell mills indexed and seated correctly during face milling, boring, and surface milling operations. Machinists and tool room technicians install this screw as part of standard arbor tooling setups on vertical and horizontal milling machines.

This shell mill arbor screw is suited for use in machine shops, job shops, and production environments where shell mill arbors are standard tooling. It is a single-piece fastener sold individually, making it a practical replacement or spare for existing arbor tooling assemblies. It applies to setups requiring a 1/2 inch pilot diameter arbor with 1/4-28 thread engagement.

Installation Notes

Installation is performed by machinists or toolroom technicians during arbor tooling assembly or cutter changeover. Always power down and lock out the milling machine before removing or installing arbor hardware. Use the appropriate hex key or spanner to achieve proper seating without over-torquing the fastener. Inspect the arbor threads for wear or damage before installation.
