Bosch 3603313501 Collet Nut

Product Description

The BOSCH 3603313501 is a collet nut designed for use with Bosch rotary tools and die grinders. A collet nut secures the collet assembly against the tool spindle, clamping the bit or accessory shank firmly in place during operation. A properly functioning collet nut is essential for safe, accurate, and vibration-free tool performance. This is an OEM replacement part manufactured to Bosch specifications, making it a direct-fit option for restoring tool function when the original nut is worn, damaged, or lost.

This collet nut is suited for professional tradespeople and skilled users who service their own Bosch rotary or die grinder tools. It is a standard maintenance and repair component, typically replaced when tool runout increases, bit retention becomes inconsistent, or the nut threads show wear. Installation is straightforward and requires no specialized equipment beyond the appropriate wrench or collet nut tool.

Installation Notes

Installation should be performed by a qualified technician familiar with Bosch power tool service procedures. Disconnect the tool from all power sources before servicing. Use the correct collet wrench or spindle lock to prevent spindle rotation while seating and tightening the nut. Do not overtighten, as this can damage the collet or spindle threads.
