Threaded key inserts, Need hard material
(OP)
I am looking for a 400 series S/S Key insert or some other material that is more durable, all that I have been able to find is carbon steel and 303, which both are not sufficiant for my needs. Any help with vendors would be greatly appreciated.
Thanks
Dale

But I'll hazard to guess these may be vendor parts numbers and/or "specials" that will have limited sources and availability (and higher costs/leadtimes) compared to the MS and NAS standard part numbers. The MS and NAS parts are relatively readily available as "Stock" items from multiple distributors, and largely available due to the distributor's volume purchasing) in quantities less than the full production run/setup that a manufacturer is probably going to want to charge you for a "special".
If your quantity requirements are less than staggering and you can live with any of the standard materials, I'd strongly suggest the specification/use of the MS or NAS parts.

Make sure you have the proper length bolt. Never run a fixture with too short a bolt. You should ALWAYS have at least 1.5D of thread engagement, but do not exceed maximum engagement depth as damage to the vibe table will usually result.
Make sure you have torqued it to the proper torque. running a fixture with incorrect torque can lead to excessive movement of the payload and poor coupling if it is too loose, and can break heads off if it is too tight. Ideally you want to torque to around 85%-90% of yeild. This leaves little margin for error, final torquing should therefore be done with a calibrated micrometer type torque wrench, not an impact gun.
