ASTM A325
Scope The ASTM A325 specification covers high strength heavy hex structural bolts from ½” diameter through 1-1/2” diameter. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts. Refer to the Structural Bolts page of our site for thread lengths and other related dimensions. This specification is applicable to heavy hex structural bolts only. For bolts of other configurations and thread lengths with similar mechanical properties, see Specification A 449. Bolts for general applications, including anchor bolts, are covered by Specification A 449. Also refer to Specification A 449 for quenched and tempered steel bolts and studs with diameters greater than 1-1/2"" but with similar mechanical properties.| TYPE 1 | Medium carbon, carbon boron, or medium carbon alloy steel. |
| TYPE 2 | Withdrawn November 1991. |
| TYPE 3 | Weathering steel. |
| T | Fully threaded A325. (Restricted to 4 times the diameter in length) |
| M | Metric A325. |
| SC | Slip critical connection. |
| N | Bearing type connection with threads included in the shear plane. |
| X | Bearing-type connection with threads excluded from the shear plane. |
| Size | Tensile, ksi | Yield, ksi | Elong. %, min | RA %, min |

| Note: Nuts conforming to A194 Grade 2H are a suitable substitute for use with A325 heavy hex structural bolts. The ASTM A563 Nut Compatibility Chart has a complete list of specifications. | ||||
Dedicated to the heavy duty earth checkings.
Screw into the ground and connect your 4 mm banana plug.
As this earth rod screws into the ground the user gets a better electrical contact with the ground (the usual smooth earth rods may make a gap around the shaft), he doesn’t need to carry a (heavy) hammer, and he can extract easily the rod if it’s driven into a root.
The 4 mm banana jack connects to 4 mm banana plugs and offers a more reliable connection than an alligator clip (the user can still connect an alligator clip if he wants), it complies with most of the 4 mm banana plugs (shrouded or not) (stackable or not) on the market.
Thanks to the big wide handle, the user can extract the rod from the ground with his the two hands.
Thanks to its sharp hard tip, the rod can be driven into the hard grounds.
The design is strong and stainless thanks to the soldered steel parts with zinc coating, it’s made for the heavy duty.
