F3125 Grade A325 is a Heavy Hex Head Style Bolt with a minimum Tensile Strength of 120 ksi. and can come in one of two types (Type 1 or Type 3). We currently stock only Type 1 so this information will be limited to a discussion of that type. Chemical Requirements (TYPE 1) Heat Analysis 120 ksi, % 150 ksi, % Carbon …

Galvanized anchor bolts are used in situations where the bolts will be exposed to any form of corrosive elements. This most often means being installed outside where the weather can cause rust. Galvanized anchor bolts are less expensive than 304 stainless steel anchor bolts, and in most situations match the galvanizing of the light poles. Light poles anchor bolts are a prime example, the anchors used to secure a light pole are exposed to the elements and require galvanizing to withstand the corr …

We stock many different sizes of hot dip galvanized bolts for rush delivery (stock list).

All of our steel bolts are made in the USA from Domestic material. We have chemical and physical certs for all of our grade A36, grade 55 and 105. We will let you know if certs are not available for any item. It is always best to ask for certs with the original order. We can certify any stainless bolt we make but some of our stainless is imported. We can use domestic if requested. We charge 25.00 for certs ordered with the parts and 50.00 if they are requested at a later date.Most of our n …

Note: Most of our Anchor bolts are roll threaded. Roll threading an anchor bolt produces a stronger thread and weighs less than a cut threaded anchor bolt. The threads are stronger because roll threading is actually forming the threads and cold working the metal. It pushes the root of the thread down and the crest up. Rolled threads are clean and smooth and don’t create any waste in the form of shavings. The material diameter of Rolled anchor bolts is normally about the same as th …
