Hex Bolts and Nuts Manufacturer in China

Source hex bolts, structural bolts, flange and socket-head bolts, hex and nylon lock nuts and threaded rods directly from our factory in Handan, China — DIN, ISO and ASTM standards, M6 to M36.

Hex bolts, structural bolts and nuts from one catalog

WTFasteners — Hebei W.T Fasteners Co., Ltd. — lists a complete bolting range from its Handan factory: hex bolts to DIN 931 and DIN 933, structural bolt assemblies to ASTM A325 and DIN EN 14399 for steel construction, flange bolts to DIN 6921, and socket head bolts to DIN 912 / ISO 4762 for machinery applications. Matching nuts are cataloged alongside: hex nuts to DIN 934 / ISO 4032, nylon insert lock nuts to DIN 985, and flange nuts — so a bolted joint can be quoted as a matched set rather than pieced together from several suppliers.

Threaded rods to DIN 975 / 976 round out the range for suspension, anchoring accessories and cut-to-length applications. Metric sizes run M6 through M36 across bolts and rods, with metric and inch sizes listed in the catalog. Property classes and grades follow the applicable standard for each item and are confirmed per inquiry, keeping quotations anchored to a named specification.

Finishes matched to the environment

Catalog finishes include black oxide for a clean, lightly protected appearance, bright zinc plating for general indoor and sheltered use, and hot-dip galvanizing (HDG) where heavy corrosion protection is required — outdoor steel structures, infrastructure and marine-adjacent projects. Dacromet and Ruspert coatings are also listed for relevant items. Confirm the finish against the service environment and the mating nut and washer combination when you send the inquiry.

Where bolts and nuts are used

Structural bolts serve steel buildings, bridges and industrial plants; standard hex bolts and nuts cover machinery assembly, automotive applications, racking and general fabrication; threaded rods are used for suspending services, formwork and chemical-anchor accessories. Wholesalers typically stock the fast-moving DIN 931/933 and DIN 934 combinations, while project buyers order matched bolt–nut–washer sets to a take-off. Carton, bulk-bag or private-label packing is aligned before shipment.

How to request a quotation

Send the product type, standard, diameter and length (or nut size and style), material and property class, finish, quantity, packing requirement and destination port or country. For structural assemblies, include the joint or connection details so the correct bolt–nut–washer combination is quoted. Drawings and non-standard dimensions are reviewed against the factory program.
