Required tool for Shimano set screw?

Jighead61 · February 26, 2018, 01:59:35 AM

I was working on a customer's Stradic (ST-2500HGFK) spinning reel today and ran into an issue. The bearing bushing is held in place by a set screw on the main shaft which needs to be removed. That set screw is tiny. I'm assuming it's a hex, but I'm not sure. Does anyone know the correct tool and size? Thanks.

On a Sustain 5000 FG hex key .035 is it. My guess is it's probably the same.

I don't know the actual size but it will be metric not imperial. If it's hex the smallest size I've ever come across is 1.3mm (.051") but they do get as small as .7mm (.028"). If it's torx T4 was smallest I've seen (but they do get as small as T1). I have complete sets of metric and imperial hex as well as torx. My slotted screwdrivers range from 1mm to 15mm (never used that one yet). You can't have enogh tools

If Twotone is correct that .035" equates to a .9mm hex

I concur with the above, IIRC it is technically .89mm, but .9 is near enough.
WIHA small hex screwdriver sets have the correct size. I think someone used the head of a sewing needle in a pinch.

A tiny flathead will do it. I buy the .9mm tool for working on RC cars.

I called Shimano this morning and they confirmed it's a 0.9mm hex. And not surprisingly (after many phone calls) no one locally carries it. Regardless, I appreciate everyone's help.

years ago, i foolishly accepted one one of these reels to service. i took the smallest hex bit i had and painstakingly filed it down to fit.

Wiha .9mm (one of the preferred metric hex sizes):

Walmart has them for $4.99

Yep, r/c car tool works.. about $5 each at local hobby store.. this is another really expensive hobby.. I can actually "fly" the one on the left (Associated truggy) by braking when 6 to 10 feet in the air as it has a slowing effect on the gyroscope action of the wheels spinning through the air altering nose up or down when landing.. Now if I can just get the casting timing right on my 6/0 senator hehe...

Carl I was into the RC cars myself. The Traxxass were all I had. 70 mph was the norm for these 4 wheel drive Slash models.

I was a slot car man back in the early 70s - happy days

The traxas will do well over 100mph with a gear change and road tires.. the associated is geared around 45mph top speed as it is designed as a "dirt-track" car.. there are great youtube videos of guys getting hit by their own cars... It's always funny till someone gets hurt, then its hillarious.... (If you can't die while doing it, it's not a sport)
