About Jiaxing Musteel Hardware Co., Ltd. - Fasteners Supplier in China

Jiaxing, China hosts Jiaxing Musteel Hardware Co., Ltd., which lists ten active products across the fasteners family. The catalogue groups items under the top categories of Fasteners, Nuts, Bolts, Screws and Washers, reflecting a typical metric and imperial fastener portfolio. Each entry is linked to an HS‑code series - mainly 7318.15 for bolts and rods, 7318.16 for nuts and 7318.21 for washers - which aligns with the international tariff classification for metallic fasteners. The supplier’s product titles reference widely recognised standards such as DIN 6921, DIN 933, DIN 912, DIN 6923, DIN 125A, ASTM A563, ASTM A193, ASTM F436 and ASTM A325, indicating the technical basis of the listings. Materials are specified for most items, for example carbon‑steel grades 8.8 or 10.9 for DIN bolts and alloy‑steel ASTM A193 Grade B7 for threaded rods.

The ten catalogue items include DIN6921 Hexagon Flange Bolts (HS 7318.15, carbon steel 8.8/10.9), DIN933 Hexagon Head Bolts (HS 7318.15, carbon steel 8.8/10.9), DIN912 Hexagon Socket Head Cap Screw (no HS code provided), ASTM A563 Heavy Hex Structural Nut (no HS code provided), DIN6923 Hexagon Flange Nut (HS 7318.16, carbon steel), DIN985 Nylon Insert Hex Lock Nuts (no HS code provided), ASTM A193 Threaded Rods (HS 7318.15, alloy steel B7), ASTM F436 Hardened Structural Washers (no HS code provided), DIN125A Flat Washer (HS 7318.21, carbon steel grade depending on application) and ASTM A325 Heavy Hex Structural Bolts (HS 7318.15, high‑strength medium carbon steel). The list combines metric DIN parts and US‑based ASTM specifications, a common mix in Chinese fastener exporters.

Product Range and Specialties of Jiaxing Musteel Hardware Co., Ltd.

The catalogue covers standard hexagon head bolts, flange bolts, socket head cap screws, structural nuts, lock nuts with nylon inserts, threaded rods, and flat and structural washers. In the fastener market, DIN‑type bolts are typically supplied in grades 8.8, 10.9 or 12.9, with tensile strengths of 800, 1000 or 1200 MPa respectively, while ASTM A325 bolts are classified as high‑strength structural fasteners with a minimum tensile strength of 830 MPa. Washers such as DIN125A are offered in carbon‑steel thicknesses from 0.5 mm to 2 mm and are sized to match M4‑M36 bolt diameters. Lock nuts like DIN985 usually incorporate a nylon collar that provides a prevailing torque of 10‑30 % of the bolt’s preload. These grades and dimensions represent the typical specifications buyers expect when sourcing industrial fasteners from China.

Trade and Export Information - Jiaxing Musteel Hardware Co., Ltd.

China is the world’s largest exporter of fasteners, and HS chapter 73 (articles of iron or steel) - especially headings 7318.15, 7318.16 and 7318.21 - captures the majority of bolt, nut and washer shipments. Major import regions include North America, the European Union, Southeast Asia and the Middle East, where automotive, construction and machinery manufacturers source high‑strength fasteners. Buyers usually require ISO 9001 quality‑management certification, CE marking for EU markets, and compliance with the relevant DIN or ASTM standards cited in the product description. Fasteners are commonly packed in cardboard cartons of 500  -  1 000 pcs, shrink‑wrapped, and palletised for 20 ft or 40 ft container loading under CIF or FOB terms. Chinese exporters often provide mill‑test certificates (MTC) and third‑party inspection reports to satisfy customs and buyer quality checks.

Sourcing from Jiaxing Musteel Hardware Co., Ltd. - Buyer Guidance

When sourcing from Jiaxing Musteel Hardware, request a current mill‑test certificate that confirms the chemical composition and mechanical properties of the declared grade (e.g., 8.8, 10.9, B7). Verify that the product dimensions, thread pitch and head style match the applicable DIN or ASTM standard, and ask for a compliance statement covering ISO 9001 or other relevant certifications. Samples of critical dimensions such as bolt length, thread tolerance and washer thickness should be inspected before confirming a bulk order, and the packaging details (carton count, pallet configuration) should be aligned with the buyer’s logistics plan.

What fastener categories does Jiaxing Musteel Hardware list?

The supplier lists bolts, screws, nuts, threaded rods and washers, covering DIN and ASTM specifications across ten individual SKUs.

Which international standards are referenced in the catalogue?

Product titles cite DIN standards (e.g., DIN 6921, DIN 933, DIN 912, DIN 6923, DIN 125A) and ASTM standards (e.g., ASTM A563, ASTM A193, ASTM F436, ASTM A325).

What HS codes apply to the listed items?

HS 7318.15 is used for most bolts and threaded rods, HS 7318.16 for flange nuts, and HS 7318.21 for flat washers. Items without an HS code in the catalogue still fall under chapter 73 for steel fasteners.

Which certifications should a buyer request from this supplier?

Buyers should request an ISO 9001 quality‑management certificate, a mill‑test certificate for each grade, and, where required, CE conformity evidence for EU shipments.

What lead time can buyers expect from a Chinese fastener supplier?

Lead times generally range from 20 to 35 working days after order confirmation, subject to material availability and any required testing.

How can a buyer obtain material test reports?

Material test reports are provided as PDF attachments upon request; they detail chemical analysis, tensile strength and hardness in accordance with the cited DIN or ASTM grade.
