This is the GB/T 799 anchor bolt (straight/hooked) product page. GB/T 799 is the Chinese standard for cast-in anchor bolts. We supply metric GB/T 799 — sizes made to order cover M16–M36 (partially threaded); carbon steel in property classes 4.6 / 8.8, materials Q235 / 45#, finishes black oxide or galvanized. Unit weights are geometry-based estimates.
US-standard reference: ASTM F1554 is the US standard for anchor bolts, in three yield grades — Grade 36 / 55 / 105 (yield 36 / 55 / 105 ksi); ASTM A307 is the US carbon-steel bolt standard. We supply only metric GB/T 799; imperial ASTM sizes are not in our catalogue. F1554 / A307 serve as a reference entry point for US-spec buyers.
Ordering checks (critical): ASTM F1554 / A307 use an imperial Unified Coarse thread, which is not interchangeable with the metric thread of GB/T 799. On an F1554 inquiry, confirm three things: (1) grade (Grade 36 / 55 / 105); (2) configuration (hooked / straight / anchor plate) and embedment; (3) matching nuts and washers. We supply metric GB/T 799 and confirm each item with you on order.

FAQ
Can you supply to ASTM F1554?+
We supply metric GB/T 799; imperial ASTM sizes are not in our catalogue (no imperial SKUs in our library). F1554 serves only as a reference entry point for US-spec buyers. On an F1554 inquiry we supply metric GB/T 799 and confirm, item by item, the grade (Grade 36 / 55 / 105), configuration (hooked / straight / anchor plate) and matching nuts and washers.
Are F1554 and GB/T 799 interchangeable?+
Not directly. GB/T 799 uses a metric thread while F1554 uses an imperial Unified Coarse thread — the two thread systems are not interchangeable. F1554 is also split into three yield grades (Grade 36 / 55 / 105). Confirm dimensions, grade and configuration when substituting.
