ASTM A325 / A325M Heavy Hex Structural Bolts The bolts are intended for use in structural connections. These connections are covered under the requirements of the Specification for Structural Joints Using ASTM A325 Bolts, approved by the Research Council on Structural Connections, endorsed by the American Institute of Steel Construction and by the Industrial Fastener Institute. Dimension: ASME B18.2.6 (Inch Size),  ASME B18.2.3.7M (Metric Size) Thread Size: 1/2"-1.1/2",  M12-M36, with various lengths Grade: ASTM A325 / A325M Type-1 Finish: Black Oxide, Zinc Plating, Hot Dip Galvanized, Dacromet, and so on Packing: Bulk about 25 kgs each carton, 36 cartons each pallet Advantage: High Quality and Strict Quality Control, Competitive price,Timely delivery; Technical support, Supply Test Reports Please feel free to contact us for more details. In 2016, ASTM A325 was officially withdrawn and replaced by ASTM F3125, in which A325 now becomes a grade under the F3125 specification.  The F3125 specification is a consolidation and replacement of six ASTM standards, including; A325, A325M, A490, A490M, F1852, and F2280.  Prior to its withdrawl in 2016, the ASTM A325 specification covered high strength heavy hex structural bolts from 1/2″ 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.  This specification is applicable to heavy hex structural bolts only. For bolts of other configurations and thread lengths with similar mechanical properties, see Specification A449. Bolts for general applications, including anchor bolts, are covered by Specification A449. Also refer to Specification A449 for quenched and tempered steel bolts and studs with diameters greater than 1-1/2″ but with similar mechanical properties.

    In July of 2009, I had just arrived in Paris and went to go see the Eiffel tower. I sat down in the Champ de Mars and set up my tripod and camera to take a nice sunset timelapse of the tower. After the time-lapse had begun, I quickly noticed that a storm was moving in and figured that I would get a chance to capture a bolt of lightning hitting the tower. I figured I was safe with my tiny metal tripod on the grass….at least until the rain moved it.

    I was able to capture a few bolts directly hitting the tower and had to run for cover when the skies opened up and there was an absolute downpour.
