Side Cover Screws

[speedblock]

All the screws on my Buffalo are effectively wasted, I will be replacing them all as part of my rebuild. Has anyone used a set like this from eBay:

Thanks,

If I recall, there may be a couple of omissions, but it is 99.9% correct.

Chris, I also switched all of my engine screws to stainless allen heads. As long as you're not going for 100% original it does make maintenance work a LOT easier. I took my old screws to a local nut and bolt shop and after about $60 US I had everything I needed.

That's what I do also There are several jobbers here in town with good metric selections - most of them deal with Spaenaur who are one of the larger suppliers up here. This is a link to one of the pages in their catalogue covering machine screws, but of course they also have allen head, as well as hex head bolts, washers, etc.

I replaced all my screws on my 350 project with buttonhead screws.5 or 6 mm allen key,a flatter head than phillips.have a look next time you are in your hardware shop.it may interest you.

I attempted to get the correct phillips head cover screws from Spae-Naur years ago....but the heads were NOT correct compared to the stock screws that the Japanese typically use. Spae-Naur had a little note in their catalogue that the heads on their screws were to US standards and nothing else.
I ended up getting the correct screws in bags of 10 for each size from a m/c parts distributor we deal with at work. Good quality, correct head profile and available in lengths up to 100mm in the M6 size, which covers everything I've ever needed.
I have one of those little divider-type bins with all my M6 case screws in it in various lengths. Sure is a time saver, IMO.

Side-by-side comparison of oil pump cover screw:

Measured screw head diameters: original is .343" & Rimfire is .340".

Reasonable price. T250/T350 kit has 22 screws & is $32 for stainless & $22 for mild steel. Used PayPal for order & shipping is about $5.

They have other kits, including T500/GT500, GT550 & GT750.

Looks like a good resource - thanks !

One of the more obvious ways to protect your investment, and the original style screws, is to buy a proper no. 3 Phillips screwdriver. So many damaged screws, are the result of the wrong tool being used, ie, no. 2 phillips. Using a manual impact driver (non-air) helps too. Those steel screws into aluminum cases, always require more torque to undo than is used to put them in. On that subject, does anyone know if there is a source for longer impact bits for the hammer driven variety of driver? Some of the case screws are deep enough, that the standard issue 1" bit won't reach. A 3 or 4" version would. I've seen them, I just don't know where to buy them. Hey Rick, do any of the catalogues have such a thing, std 1/4" hex is what most of them use. Cheers.

I have to say that this is something I've looked into from time to time over the years.....with no success, so far. My 40 year old Japanese made driver has the long bits and the #3 Posidrive bit is still in good condition....but that could change without warning, of course. My particular drive uses a special flat tang-type drive which makes matters even worse.
Spae-Naur offers a #3 Phillips bit with 1/4" drive in 2", 3" and 6" inch lengths "to fit most popular makes of air and electric drivers"..... although how they would last, I cannot tell.
Part numbers are 876-1185, 876-840 and 876-1186 respectively. Greg at Blackfoot Industrial can get those for you.

I suppose folks know that as originally supplied, the screws used are made to the JIS standard (Japan Industry Standard), and actually were not Phillips ? They are close, but not quite the same which is why they often are damaged when using a Phillips screw driver. Also the small 'dimple' on the screw head means the thread conforms to ISO standard, but the correct tool required is JIS standard - prior to about 1966 or so, the thread pitch was JIS also.

You can buy JIS screw drivers, although I don't personally know anyone that has -usually a quality Phillips works fine.
