In 2016, ASTM A325 was officially withdrawn and replaced by ASTM F3125, in which A325 now becomes a grade under the F3125 specification.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.

This is the Taree Rd level crossing at Wingham NSW. It is located on the North Coast line between Newcastle and Brisbane, and is about 12km from Taree. The signals here were installed around 1958, this being one of the first crossings in NSW to receive gates. Although some of the equipment has been renewed, this is most likely the oldest surviving installation in NSW.
Both gated signals have Western Cullen Hayes gate mechanisms which replaced the original WRRS/GRS Type B ones. Some time ago both of the masts were relocated to new foundations, most likely to allow for road widening. One of the original foundations can still be seen on the northern side of the crossing.
The signal on the southern side of the crossing has an unmarked base. The front facing lights were made by Westinghouse and the rear facing lights by McKenzie & Holland. The signal has a Western Cullen Hayes mechanical bell which is the only bell at the crossing. This is unusual as most gated crossings in NSW have 2 bells.
The gated signal on the northern side has a WRRS base. The lights are a mixture of old and newer McKenzie & Holland ones. The signal also has a very old and faded “1 Track” sign which is rare, as crossings with only 1 track normally don’t have a sign.
There is a second signal on the northern side of the crossing to assist with sighting due to the bend in the road. As well as a “1 Track” sign, it has a pair of very old McKenzie & Holland lights which were an earlier design. They can be identified by the hole at the back of the lamp housing which contains a bolt to secure the door.
