In 2016, ASTM A325 was officially withdrawn and replaced by ASTM F3125, in which A325 now becomes a grade under the F3125 specification.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.
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| TYPE 2 | Withdrawn November 1991.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) |

Product Description
Pulsar by Seiko Holdings Corporation.
A spectacular breakthrough
Pulsar was born in an age of optimism. In the 1970′s, everything seemed achievable through the rapidly growing technological expertise at the world’s fingertips. Space flight had been converted from dream to reality, computer science was developing at break neck speed and electronics seemed to deliver new advances every day. Pulsar symbolized the age. It was new and it was bold, it was surprising and it was different. Pulsar, the world’s first electronic digital watch, created a sensation when it was unveiled in New York in 1972 and it changed the world’s perception of time.
A tradition of difference
When the brand was taken into the Seiko Corporation in 1980, it brought further surprises to the world; the first calculator watch in 1980 and the first all-quartz watch line in 1981 were among its industry-leading achievements. And throughout the ’80′s and 90′s Pulsar continued to bring to market new products that were born to be different. The Avant-garde collection in 1980′s set a new style in women’s watches and Spoon in 1990′s were unique designs which further cemented Pulsar’s image as an ingenious and surprising watchmaker.
Towards a modernist future
Today, Pulsar remains loyal to its heritage. It was born to be different and it will remain so. Each Pulsar watch has the hint of the futurism and modernity that have always been its hallmark. Pulsar is a brand for the individual who appreciates real value and seeks quality with individuality and flair.
