Default Pinion set screw size

In the interest of accuracy I'm using CRC pinions, I'm looking to buy a single allen driver for the set screw in the pinion gear. A set will do, but all I really need is the 1 driver.

I prefer the ball end drivers like Bondus has, any help with driver brand or sizing would be a great help.

(not home right now other wise I'd find it with my caliper.)

Been using my 1.5mm driver and it has a sloppy fit, I've even striped the driver end of more than a few set screws. Can't find my L shaped allens to confirm sizing, but the last time I used the L shaped allen it was the correct size, and fitment was snug as it should be.

CRC pinions have both 4-40 and metric set screws. Its quite a pain. I have CRC pinions from 60 to 80, bought at different times. The 70-80 are all metric and need a 1.5mm driver like my Trinity pinions and my 60-69 old pinions are all 1/16 wrench like PRS. I bought a new 62 last week and it uses a 1.5mm driver.

why could they not just stay with one size? either one would have worked, but not knowing which is which, is a pain.

Set screws come in 3 sizes: 050, 1/16th, and 1.5mm. CRC does everything except for their F1 in standard sizes so likely it is .050 or 1/16th.

"CRC redefines the racing pinion.....

The "Gold Standard" in pinions. CRC's new pinion gears are super lightweight, true and precision CNC machined in 7075 aluminum. We have completely removed all unnecessary material in an effort to produce the lightest pinion available. The face is undercut all the way out to the teeth diameter. Then on the larger pinions, the undercut face is scalloped in a triangle design to remove even more material. Complete with a 5-40 UNC set screw (1/16 inch wrench), each gear has the tooth number laser etched on the barrel."

they are not all 1/16 anymore. I have at least 10 pinions from CRC that use 1.5mm. I agree they are a good quality product and really like them, but dont count on them being 1/16 or 1.5 mm. You may need both. they sell a complete set with tree https://www.teamcrc.com/crc/modules....prodID=7719279 and https://www.teamcrc.com/crc/modules....prodID=7719278 for different ranges.

My pinions are the same way. Seems like the newer set screws are 1.5mm. Really strange to see a 5-40 with a 1.5mm head, but I love it. Can get rid of the 1/16th out of my bag. I'm wondering if they sell the newer set screws separately so I can replace the 1/16ths.

I only have a couple of CRC pinions but both are 5-40 1/16th but REALLY tight on that 1/16th. Makes you think it's a 1.5 but it's not.

Yeah the new ones are definitely 1.5mm. You can visibly see the difference in size when held next to each other.

I noticed my CRC pinions don't all use the same size screw. Now I know I'm not crazy.

CRC pinions are supposed to be 5-40 using a 1/16" wrench. Apparently some of the set screws were broached with a 1.5. If you would like the 1.5 x 5-40 set screws replaced, CRC will do so free of charge. Send the incorrect set screws, either in a baggie or tape them to a piece of paper and send them to:
