Hi John Used a wench of Chinese origin, was very lightly case hardened so was possible to drill with a normal HSS drill bit in a battery drill. Would never attempt to do so with one of US manufacture. I repair a lot of kit that use SMA and SMC connectors and being a nerd I like to torque the connectors up correctly which in the case of SMA is 5 in-lbs for brass ones and 10 in-lbs for stainless steel ones..

Did you drill that wrench handle as-is, or after heating and annealing so it drilled more easily?? Or is it not a drill hole I see there? |

We torque our stainless steel SMAs to 8 in-lbs, not 10.

Regarding 5/16 inch wrenches with the slot to slip over coax, Mini-Circuits part number HT-4-SMA is about $37.? Nice knurled handle for good grip, too.? Found one in the lab this morning.? ? HTH.? ? Jim Ford?

That is what happens when you try to use the incorrect word for a spanner. G Edmonds On Friday 12 July 2024 at 22:06:05 BST, Tom Lee <tomlee@...> wrote: She must've been very strong...

Shameless plug: I make these and sell them on eBay "SMA wrench" , eBay handle "kmec-at-aol".
Doesn't make a lot of money (some time involved), AND you can do it yourself, but I have some fun and enjoy metalwork. (You have to, if you like making microwave stuff). I also have gotten hollow shaft 5/16 Xcelite nutdrivers (yellow handle), and ground away 1/2 of the nut&barrel, makes a MOST handy tool for tightening sma connections, especially on sma relay (hard to get to the center connector with hardlines in the way).
