6mm Steel Chain Sprockets

04B 6mm British Standard pitch sprockets in the most popular sizes. Sizes we do not stock at technobots are available through our gearsandsprockets website that offers a far greater range of transmission components.

These sprockets are supplied with a pilot bore that can be machined to a larger accurate diameter (subject to boss size) although many users find the pilot bore quite acceptable. Using our 'Custom Machining' service, we can not only bore out these sprockets but also drill and tap for set (grub) screw fixing. See the 'Custom Machining' tab with each product for more information.

Nominal tooth width: 2.8mm
Boss width: 7.5 to 12mm depending on sprocket size
