Dewalt n521085 Arbor Bolt

Product Description

The DEWALT n521085 is a replacement arbor bolt designed to secure cutting or grinding accessories to compatible DEWALT power tools. The arbor bolt serves as the primary fastener that clamps blades, wheels, or discs against the arbor flange, maintaining proper seating during operation. This is a genuine DEWALT replacement part, sourced directly from the manufacturer's parts and accessories line. Licensed technicians, shop mechanics, and experienced tool service professionals install this bolt when the original fastener shows wear, stripping, or damage that could compromise accessory retention and safe tool operation.

This arbor bolt is intended for service and repair of DEWALT power tools that use an arbor-style blade or wheel retention system. Typical applications include table saws, miter saws, circular saws, and angle grinders where a threaded arbor bolt secures the cutting accessory to the spindle. It is a direct OEM replacement part, making it appropriate for restoring a tool to original factory specification.
