Portland Bolt FAQs

Class 3A Thread

Does Portland Bolt produce bolts with a Class 3A thread? What does the “A” mean in “3A”?

Dimensioned Closed Eye Bolt

Turned Eye Bolts

Do Portland Bolt eye bolts have load ratings?

Portland Bolt manufactures eye bolts to pretty much any size imaginable. The type of eye bolt that Portland Bolt makes is not forged, but is turned and can be welded shut if needed. When load ratings are provided for eye bolts, they are normally for forged eye bolts, where the eye is formed as one solid...

Rush Lead Times

Can Portland Bolt expedite my order?

Yes, Portland Bolt can rush an order though production. Portland Bolt has what we recognize as “standard lead times.” These lead times consider the manufacturing processes required to complete an order. For instance, if we are going to manufacture a 1” x 36” hot-dip galvanized ASTM F1554 Grade 36 hex-head anchor bolt with 6” of thread,...

State DOT Projects

Does Portland Bolt provide fasteners on Department of Transportation jobs?

Yes, Portland Bolt provides domestic fasteners with paperwork for DOT projects all over the US. We routinely have state inspectors from Oregon, Washington, and California in our facility inspecting and tagging orders for our customers. For contractors and steel fabricators in other states, we are able to ship the materials to the jobsite, or to... Read more

Online Ordering

Why doesn’t Portland Bolt have an ecommerce website where I can place orders on line?

While we’ve made it very easy to submit an inquiry online, we don’t have a system that allows a purchase to be made online through a few simple clicks or an online listing of prices. Portland Bolt is a manufacturer of nonstandard construction bolts, which does not lend itself to an ecommerce site. While there... Read more

Tie Rod Mounting Brackets

Does Portland Bolt manufacture the mounting brackets for tie rod assemblies?

Unfortunately Portland Bolt does not have the capability to fabricate the wall mounts to which clevises attach. These fabricated lugs need to be designed by an engineer or architect to ensure they can withstand the loads applied to the tie rod assemblies. If you have a detailed drawing of the mounting brackets, we can have them... Read more

Published Prices

Why doesn’t Portland Bolt advertise prices on the website?

Due to the fact that Portland Bolt is a manufacturer of nonstandard anchor bolts and construction fasteners, the vast majority of the product that we manufacture and sell to our customers is custom and is manufactured to the specific requirements of the job they are being used on. Portland Bolt is not a large scale,... Read more

Cargo Containers

Does Portland Bolt load containers?

Portland Bolt does not have the ability to load cargo containers for ocean freight. We have no experience in securing the contents inside so this will have to be done by a freight forwarder. We routinely load our shipments on a truck at our facility where they are sent to be loaded in a container... Read more
