51 fasteners and power line fittings, now in one catalogue
Hebei Bolaige New Material Technology Co., Ltd. has consolidated its product range into 13 categories and 51 items, covering the two product lines the company focuses on: fasteners and power line fittings.
Fasteners (6 categories): bolts, studs and rods, nuts, washers, expansion anchors and screws — from hex head bolts and carriage bolts to ASTM A193 B7 stud bolts with A194 2H nuts, flat / spring / square / fender washers, elevator and wedge anchors, drop-in anchors, drywall screws, DIN 571 wood screws, concrete screws and chipboard screws.
Power line fittings (7 categories): suspension, tension and wedge, splices and connectors, link fittings, protection, pole line and earthing, and other power hardware — from suspension clamps, tension clamps and parallel groove clamps to ball eyes, socket clevises, U-shackles, yoke plates, vibration dampers, cross-arms and grounding clamps.
ASTM A193 B7 stud bolts with A194 2H heavy hex nuts
Bolaige supplies ASTM A193 B7 stud bolts together with matching ASTM A194 2H heavy hex nuts — the standard pairing for petrochemical, refinery and flange connections where a high-strength, high-temperature bolted joint is required.
Both parts are produced to the same standard and shipped as a matched set, so the nut grade always matches the stud grade. Threaded rods to DIN 975 are available from the same production line.
When requesting a quotation, please confirm the stud diameter and length, the thread type (UNC / UNF / metric), the finish and the quantity.
Wood screws DIN 571 and concrete screws added to our screw range
Our screw range now includes two additions requested most often by overseas buyers.
Wood screws — hex head, DIN 571, M4 to M20. A deep coarse wood thread that can be driven directly into timber. Commonly used in timber construction, fencing, pergolas and solar mounting.
Concrete screws — hardened carbon steel with blue-white zinc or yellow zinc finish. These screws cut their own thread in concrete and masonry, so no plastic plug is needed.
