Pro-Tech Etched Nuts/Bolts

Charlie from Pro-Tech was generous enough to send Model Railroad Tips some sample products.  In this article we'll check out the etched nuts/bolts.

As you can see, they come packaged with a nice pink backing.

I decided to test these out on a Scale Segmental Bridge Co. [see HO Scale Concrete Segmental Bridge Side-by-Side Comparison for more] slab girder bridge.  I used the nut-bolt version, shown above on the right-most 10 rows.

Compare the Detail Associates square lag bolts provided in Scale Segmental Bridge Co. kits on the right, with the Protech etched bolts on the left.
Closer view of the Protech bolts. I painted them a rusty color before installing, right on the backing they came on on in the package. I used a tiny dab of Aleene's Tacky Glue to attach the bolts.

Over all I feel the Protech bolts are an amazing product.  The nut/bolt version I used could use a slightly more pronounced bolt in the center, but I think that's a cast-off of the etching limiting the process.  I'll continue to look for more uses for these bolts.
