Full Set Product Features & Advantages
Complete Accessories, One-stop Procurement
Our DIN603 carriage bolt assembly includes bolts, nuts and flat washers in one complete set, saving separate purchasing and matching work. All accessories are produced under the same standard with precise thread matching and perfect assembly compatibility, effectively avoiding missing parts, mismatched specifications and poor fitting problems, greatly improving procurement and assembly efficiency for bulk orders.
Multi-series Sets for Full Working Condition Coverage
Four complete series cover all usage scenarios. Electro-galvanized carbon steel sets are cost-effective for indoor dry environments. Hot-dip galvanized sets feature super anti-corrosion performance, specially designed for outdoor open-air steel structure projects. 304/316 stainless steel sets resist moisture, acid, alkali and coastal salt spray corrosion, meeting long-term outdoor and high-standard anti-rust requirements, covering light and heavy-duty, indoor and outdoor working conditions.
Anti-rotation Design & Stable Locking
Adopting the classic DIN603 square neck structure, the bolt can be automatically positioned and prevented from rotating during installation without auxiliary fixing tools. The fitting is tight and the force is uniform, avoiding loosening and slipping during long-term operation. The matched flat washer disperses pressure evenly to protect the workpiece surface from damage, providing excellent fastening stability for vibrating and heavy-duty working conditions.
Precision Technology & Unified Stable Quality
All accessories are produced and inspected by unified grading standards. Carbon steel sets are strengthened by quenching and tempering heat treatment, while stainless steel sets adopt high-purity raw materials. The threads are full and precise with consistent tolerances, ensuring strong interchangeability and stable batch quality, suitable for precision assembly and large-scale engineering construction.
Grade 4.8/8.8 Electro-galvanized Carbon Steel Set
As the cost-effective mainstream kit, it is made of high-quality carbon steel with electro-galvanized surface treatment for good rust resistance and smooth appearance. With moderate hardness and excellent toughness, it is widely used for indoor warehouse shelves, ordinary mechanical equipment, woodworking assembly and light-duty tooling structures, ideal for general industrial and civil fastening scenarios.
HDG Hot-Dip Galvanized Connection Set
Specially designed for outdoor engineering, this set adopts high-temperature hot-dip galvanizing technology with thick and uniform zinc layer, featuring outstanding salt spray resistance and weatherability. It can resist long-term wind, rain, oxidation and slight acid-base corrosion, perfectly suitable for outdoor guardrails, steel structure projects, trailer frames, agricultural machinery and other harsh open-air working conditions.
304 Stainless Steel Set (A2-70)
A cost-effective anti-corrosion solution with authentic 304 stainless steel material, delivering excellent anti-rust, anti-oxidation and moisture-proof performance without magnetization. Compliant with A2-70 strength standards, it is commonly used for humid outdoor environments, water treatment equipment, garden facilities and ordinary coastal equipment assembly, being the mainstream choice for outdoor anti-corrosion procurement.
316 Stainless Steel Set (A4-70)
High-end anti-corrosion premium kit made of 316 molybdenum stainless steel, with far superior acid, alkali and salt spray corrosion resistance than 304 steel. It adapts to severe working conditions such as coastal salt spray and chemical corrosion. Featuring high mechanical strength, wear resistance and long service life, it is widely applied in high-end outdoor projects, marine equipment and chemical mechanical equipment.
Production Process
Graded Material Selection: Select high-quality raw materials according to carbon steel and stainless steel series to ensure consistent performance of all accessories from the source.
Integrated Precision Forming: Bolts are cold-headed in one piece with regular square necks and burr-free round heads; nuts and washers are precisely stamped with unified dimensions.
High-precision Thread Rolling: All accessories adopt unified precision thread rolling technology with full thread profile and standard tolerance to ensure perfect fitting.
Graded Heat Treatment: Carbon steel products are quenched and tempered in strict accordance with Grade 4.8/8.8 standards to stabilize mechanical properties and prevent fracture and deformation.
Custom Anti-corrosion Treatment: Provide electro-galvanizing, hot-dip galvanizing and stainless steel polishing processes to meet different environmental anti-rust needs.
Full Batch Inspection & Matching: Inspect dimension, matching degree, hardness and anti-corrosion performance batch by batch, with manual precise matching and packaging to eliminate defective and mismatched parts.
Application Industries
Warehouse & Logistics Equipment: Fastening of heavy-duty shelves, warehouse brackets and logistics turnover equipment.
Outdoor Engineering Facilities: Assembly of road guardrails, garden fences, steel structure frames and outdoor curtain walls (HDG/stainless steel sets preferred).
Traffic & Vehicle Equipment: Structural fastening of trailer frames, truck accessories, agricultural machinery and engineering machinery.
General Machinery Manufacturing: Complete assembly of electromechanical equipment, woodworking machinery and light-duty tooling equipment.
High-end Anti-corrosion Equipment: Anti-rust fastening of water treatment, coastal and chemical light equipment (304/316 stainless steel sets).
