Technical Specifications & Manufacturing Excellence
1. Premium Material & Processing
-
Steel Grades: Manufactured from Carbon Steel Grades 4.8, 8.8, 10.9, and 12.9, compliant with ISO 898-1, ASTM A325, A449, and SAE J429 standards. Available in Stainless Steel 304/316 upon request.
-
Hot-Dip Galvanizing Process: Fasteners are immersed in molten zinc at approximately 450°C (842°F), creating a metallurgical bond. This produces a thick, durable coating (typically 45-85 μm) far superior to electroplating for outdoor durability.
-
Coating Quality: Meets ASTM A153, ISO 1461, and AS/NZS 4680 standards. The zinc coating provides sacrificial anode protection, preventing rust even if the coating is scratched.
2. Comprehensive Product Range
-
Hex Bolts (Hex Head Cap Screws): Full thread or partial thread, various lengths and diameters.
-
Hex Nuts: Grade 4, 8, 10, and 12 matching bolt strength grades, in regular and heavy (thick) patterns.
-
Assemblies: Bolt-Nut-Washer sets (galvanized flat washers and spring washers available).
-
Sizes: Metric (M6 to M36) and Imperial (1/4" to 1-1/2") diameters. Lengths as required.
3. Critical Quality Features
-
Consistent Threading: Precision-cut or rolled threads to ISO 965-2 6g/6H tolerance for smooth engagement.
-
Head Markings: Clear grade identification markings on bolt heads and nuts for traceability and compliance.
-
Dimensional Accuracy: Strict adherence to DIN 933/934, ISO 4014/4017, ASME B18.2.1 standards for hex width, head height, and thread length.
The bolts include hex bolts, carriage bolts, hex socket bolts, flange bolts, flange bolts, square bolts, eye bolts, T bolts, and more. The ranges of product grades are 4.8,8.8,10.9, and 12.9m and Gr2, Gr5, and Gr8. Materials are available for carbon, stainless steel, and aluminum. The diameter is from 2 to 48mm or 1/8 to 2 inches and the length is from 10 to 300mm or 3/8 to 10 inches. The standard is according to DIN, ANSI/ASME, BS, GB, and JIS, and non-standard as customer's request. The wide range choice of finishes, such as zinc plated(bright color or yellow color), hot dip galvanizing, chemical blackening, dacromet, plain, etc.
Hex Cap Screw Classification
Grade2 Hex Cap Screws
Grade2 hexagon cap screws are made of mild or medium carbon steel for non-critical applications that are not affected by extreme temperatures or stresses.
Grade5 Hex Cap Screws
Grade5 hexagon cap screws are made from medium carbon steel and heat-treated. They have a greater tensile strength than Grade2 screws.
Grade8 Hex Cap Screws
Grade8 hexagon cap screws are made from medium carbon steel and heat-treated. They have a greater tensile strength than a Grade5 screw, and designed for use in high stress applications.
Stainless Steel 18-8 & 316 Hex Cap Screws
Both 18-8 and stainless steel 316 hexagon cap screws are made from austenitic alloys. 18-8 stainless steel
screws are used in products that require general atmospheric corrosion resistance. stainless steel 316 screws
have a higher resistance to corrosion and have superior strength at high temperatures.
Class 4.6 4.8 5.8 Hex Cap Screws
Class 4.6 4.8 5.8 hexagon cap screws are made of mild or medium carbon steel.
Class 8.8 Hex Cap Screws
Class 8.8 hexagon cap screws are made from medium carbon steel and heat treated. Class 8.8 screws have greater tensile strength than classes 4.6, 4.8 and 5.8 hex bolts.
Class 10.9 Hex Cap Screws
Class 10.9 hexagon cap screws are made from medium carbon alloy steel and heat treated. Class 10.9 screws have greater tensile strength than Class 8.8 hexagon cap screws.
