Specifications
1/2" x 6-1/2" Conquest A325 Type 1 Heavy Hex Structural Bolt with Plain Finish
When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.
Conquest A325 Type 1 Heavy Hex Structural Bolts in 1/2" diameter are engineered for steel-to-steel fastening in structural applications. These bolts meet ASTM F3125 standards, providing the strength and reliability required for bridges, commercial framing, and infrastructure work.
1/2" A325 Type 1 Structural Hex Bolts for Beams, Frames, and Steel Assemblies
With 13 TPI coarse threads and a heavy hex head, these bolts offer solid clamping force and durability. The plain finish is suitable for controlled environments or temporary installations where corrosion resistance isn’t a priority. Built from carbon steel, these bolts are widely trusted in construction and steel fabrication.

Customer Reviews
Nice to find quality products in small quantities. Fast shipping as well!
I needed bolts to weld to racing seat mounting brackets that are going into a 1973 Plymouth Cuda RestoMod that will be doing charity work and promotion for trade schools. I’ve been building it for two years and getting ready to put it on the street. The seat brackets came with 5/16” factory size threaded studs but I’m upgrading the size to watch the performance of the vehicle. Safety always goes into any part of the build I’ve made. The heads of these bolts will be removed and then the threaded piece will be welded onto the seat bases making them much safer. Thank you fasteners Plus for a great product.
I would definitely recommend these folks. My order got delayed in shipping and they stepped up and took care of everything. Very professional and great customer service
