1/4" Dia. Smooth Square Head Bolt

Good quality. Fits nicely into my threaded inserts.

Coating

Not too impressed with fastener coating. The coating was thick and made it difficult to use the proper size wrench. Some of the coating came off of the bolt flats when the proper size wrench was used. The coating on threads made it difficult to install the nut. Also, it appeared that the order was completed in two batches as there was a noticeable color/finish difference between first and second batch.

quality, hard to find product

These quality, hard to find 1/4" square head bolts were just what I needed to replace a mismatched bolt on a vintage tool. I have bought here before and will again.
