Thread: Micro-Fasteners: Where to get & how to use

I’ve recently learned about micro-fasteners.

Experienced craftsman, microfasteners.com has changed all the part numbers. With the new part numbers, you can search by part number. The part number for the socket wrench for the small pattern bolts is WR0 (that’s a zero, not an O). For the large pattern it is WR00.

The numbers I’ve checked are for brass hex head screws, the nuts that fit them and appropriate wrench. Let me know if you want to know what other items are.

Please add comments to improve on this info - there are plenty of folks with more experience than I have.

Newer craftsman, microfasteners described in this post are nothing more than really small nuts and bolts. The industry calls them screws rather than bolts, which threw me off. These little fellas really help when putting new scales you’ve made together with the wedge and pinning in the razor.

The purpose they serve is to act as permanent pins so you can identify any issues without having permanently pin and then have to remove it. They are very quick to put together and take apart.

Here are a few ways I use them:

• Wedge fit - I use these to check the wedge fit when viewed from the side as well as whether there is unacceptable gap between the front of toe (end) of the scales and the wedge.
• Overall fit - I’ll put the
• whole razor together. I check:

1. Whether razor will close. I like tight tolerance between the blade and wedge. Sometimes it won’t fit when put together.
2. Whether the razor close, being reasonably centered. If it is off just a little, I can fix it when pinning. If its off a lot, then either the scale(s) are warped, the blade is bent, or most likely, once put together, the pinning holes have been pushed out of alignment.
3. How the balance feels.

The micro-fasteners won’t fit exactly as the pins do, though they are very close.

Pictured below is part number ASTJEWEL, the Jewelry Cold Connection Kit 1, at a price of $37.70. You’ll notice that I’ve checked some part numbers. These are the ones I’ve been using. These are all brass. The back row has the screws, which I think of as bolts, and the length shown. A variety of sizes is nice to have. Also checked is the small pattern nuts. These require the socket wrench WR0, which came with the kit. To the left of the small pattern nuts are larger nuts. I haven’t used them as I don’t have the wrench, which is part number WR00.

I’ve identified the part numbers so folks can order only what they need. I didn’t do the math to see if you come out ahead by getting the kit. The kit comes with 20 of everything other than the wrench, drill bit and counter sink drill bit, and it has one of each of those.

Hope this helps!

For all the time I’ve ordered from Micro-fasteners I never really paid attention to where they are located.
10-15 minutes from my house is where!
Well I was getting low and needed my usual order of 300 #0 , 200 #1 + , 100 #0 SS
Walked around Easton today and couldn’t find the place. Ironically it’s the back half of a second hand shop called grandmaw’s back porch. No other clue. But it’s directly behind the Crayola crayon factory. A fun visit too especially with my granddaughter .

Got to meet the owner and had a wonderful talk. She couldn’t for the life of her imagine just how we use her washers. Whipped out my phone and gave her a quick primer on razors . Told me she sends an unbelievable amount to Russia. Hah! How about that.
A quick stop at the hobby shop for 9 ft of rod ( a buck a foot in 3’ lengths) and I’m good for a while.

Oh and BTW what you are describing is a screw but the industry calls them “Machine Screws” as opposed to wood screws you are familiar with. That’s how they are listed. 15 yrs in a home center cleared this up.

There is also a seller on eBay who makes brass fasteners specifically for straight razor test fitting. I've used micro fasteners so far, but I plan on ordering a set of these when they become available again.

Very worthwhile info for new guys. Wish I would have had this info 10 years ago when I first started, could have saved me a lot of work and heartache.

Fastener Express is another supplier. They list dimensions & sizes.
