I need a 3/8-16 full thread (Tap) 1/2" long hex bolt with a left hand thread.
Anyone know where I can get one without paying a minimum order fee.

Do a search on "bolt" and just follow the icons.

There's another approach that might be the easiest and most practical, which I didn't think to mention earlier. In a situation like this, I'd be inclined to drill the hole a bit oversize and re-tap it for a rightie. That could be just a matter of using a larger bolt, or you could Heli-Coil the hole and use one of the same size. With something like Lock-Tite, the rotation shouldn't loosen it. There is a possibility of that throwing the rotating assembly out of balance, though.

Shipping from McMaster is not a gouge. I order from them at least 5 times a week.NoTime said:I found this 90211A292 at $7.03 instead.
Grade 8 steel.
I don't think the zinc plating will make any difference.
Also cutting the extra half inch off the steel bolt is going to be a lot easier than cutting a 1/4 inch off stainless.
Oddly the 1" stainless steel bolt is only $10 instead of $17 for the 3/4".
What is their shipping like?
Looks like the site won't tell me until *after* I put my credit card in.

I would make sure that you're not going to get the stainless bolt if the retainer it's going into is stainless. You'll end up with a galling problem.
If he'd jump around with the saw, while I sit back with a beer...:!)Danger said:Oh great...
Then you'd have Hulk Hogan jumping around in your saw.
It may not be too much of an issue if it is just a nut and bolt. It gets a lot worse with things like pipe fittings and hydraulic fittings that have large thread surfaces. It will most likely just seem like they are tough to get apart.NoTime said:Thanks.
I'm always leary of shipping charges.
Seems like too many places make up for the low price in shipping.
Stainless screws with stainless nuts is an issue?
I never heard of that, but I learn a lot poking around here.
How bad a problem is it?
Hmmm... I wonder if it might involve Van der Waals forces? I wouldn't expect any kind of chemical reaction.Q_Goest said:I'm not sure what exactly the process is at the microscopic level
Yea! On drilling the stuff.Danger said:Hmmm... I wonder if it might involve Van der Waals forces? I wouldn't expect any kind of chemical reaction.
I'm quite unfamiliar with stainless steel, other than knowing that I don't ever want to try working with it again. I had some 16# stainless plates made up one time to cover the holes where locks had been removed. It took me 3 hours and half a dozen bits to drill 4 stupid little 3/32" holes for the mounting screws (for one plate).
Tungsten carbide is good, cobalt drills are best. Use a lubricant when drilling steels.Does anyone know good drill bit for this purpose?
A left hand thread is a type of thread where the threads on the bolt or tap turn counterclockwise to tighten instead of the traditional clockwise direction.
In this context, "3/8-16" refers to the diameter and thread pitch of the bolt. The first number (3/8) represents the bolt's diameter in inches, and the second number (16) indicates the number of threads per inch.
A full thread refers to a bolt or tap that is threaded along its entire length, as opposed to a partial thread where only a portion of the bolt is threaded. In this case, the 3/8-16 bolt is threaded for its entire length of 1/2 inch.
The acronym MOQ stands for "minimum order quantity". The description states that there is no MOQ, meaning that there is no minimum number of bolts that must be purchased in order to place an order.
This type of bolt is often used in applications where a traditional right hand thread may loosen or become damaged due to vibrations or torque. It is commonly used in automotive and industrial machinery, as well as in situations where a bolt needs to be tightened in a counterclockwise direction.
