Premium 10 mm Hex Bolt – High-Strength Fasteners for Industrial Applications
Product Overview
Our 10 mm hex bolt is a precision-engineered fastener designed for demanding industrial environments. Manufactured from high-grade carbon steel, alloy steel, or stainless steel, these bolts feature a standard hexagonal head and a fully threaded shank, ensuring secure clamping and reliable load distribution. Whether you are assembling heavy machinery, constructing steel structures, or maintaining automotive equipment, this 10 mm hex bolt delivers consistent performance under stress. Each bolt meets ISO 898-1 and ASTM A325 specifications, guaranteeing dimensional accuracy and mechanical integrity.
Key Features
- Precision Threading: Consistent 1.5 mm thread pitch (M10 x 1.5) ensures smooth engagement with standard nuts and tapped holes, reducing installation time.
- High Tensile Strength: Available in grades 8.8, 10.9, and 12.9, with tensile strengths ranging from 800 MPa to 1,200 MPa for heavy-duty clamping.
- Corrosion Resistance: Options include plain finish, zinc-plated (clear or yellow), hot-dip galvanized, and stainless steel (A2-70 or A4-80) for outdoor or marine use.
- Dimensional Accuracy: Hex head width across flats (16 mm) and height (6.4 mm) comply with DIN 933/931 and ISO 4014 standards.
- Full Threading: Shank length fully threaded from underhead to tip, providing maximum grip length for vibration-prone assemblies.

Application Scenarios
The 10 mm hex bolt is a versatile fastener used across multiple industries:
- Construction & Steel Structures: Securing steel beams, scaffolding, and guardrails where high shear strength is required.
- Automotive Assembly: Engine mounts, chassis components, and suspension systems benefit from the bolt's vibration resistance.
- Heavy Machinery: Fixing gearboxes, pumps, and conveyor systems in mining, agriculture, and manufacturing plants.
- Energy Sector: Wind turbine towers, solar panel frames, and pipeline flanges demand corrosion-resistant stainless steel variants.
- DIY & Furniture: Workbenches, industrial shelving, and gym equipment rely on the 10 mm hex bolt for durable connections.
Advantages
- Superior Clamping Force: The coarse M10 thread provides optimal preload without stripping, even in soft materials like aluminum.
- Heat Treatment: Alloy steel bolts undergo quenching and tempering to achieve consistent hardness and fatigue life.
- Interchangeability: Fully compatible with standard M10 nuts, washers, and hex tools (16 mm socket/wrench).
- Cost-Effective: Bulk manufacturing with strict QC reduces per-unit cost while maintaining ISO tolerances.
- Traceability: Each batch is marked with grade and manufacturer code for quality audits and recall management.

FAQ
Q: What is the difference between grade 8.8 and 10.9 for a 10 mm hex bolt?
A: Grade 8.8 is medium-carbon steel with a tensile strength of 800 MPa, suitable for general construction and automotive use. Grade 10.9 is alloy steel heat-treated to 1,000 MPa, ideal for high-stress applications like engine blocks or heavy equipment.
Q: Can I use a 10 mm hex bolt with a standard 10 mm nut?
A: Yes, the M10 x 1.5 thread pitch is a universal standard. Always pair with a Class 8 or 10 nut (depending on bolt grade) to ensure proper load distribution.
Q: How do I choose the right length for my application?
A: Measure the total thickness of materials to be joined, then add at least 10 mm for full thread engagement beyond the nut. For example, a 30 mm stack requires a 40 mm long bolt.
Q: Are these bolts suitable for outdoor use?
A: Yes, but we recommend hot-dip galvanized or stainless steel (A4-80) for coastal or chemical environments. Zinc-plated bolts are adequate for dry indoor applications.
Q: Do you offer sample orders?
A: Absolutely. We provide free samples for up to 10 pieces per size/grade. You only pay for shipping. Contact our sales team with your requirements.
Q: What is the minimum order quantity (MOQ)?
A: For standard carbon steel 10 mm hex bolts, MOQ is 500 pieces per length. For stainless steel or custom coatings, MOQ is 2,000 pieces. Smaller quantities are available through our distributor network.
