High-Strength M6 x 60mm Hex Bolt | Precision Fasteners for Industrial Assembly
1. Product Overview
The m6 x 60mm hex bolt is a metric fastener designed for demanding mechanical and structural applications. Featuring a standard M6 thread pitch (1.0mm) and a 60mm shaft length, this bolt provides the ideal balance between grip length and clamping force for medium-load assemblies. Manufactured from high-grade carbon steel or stainless steel, it undergoes stringent quality control to ensure dimensional accuracy per DIN 933/ISO 4014 standards. Whether used in machinery, automotive sub-assemblies, or construction frameworks, this hex bolt delivers reliable torque retention and vibration resistance.
2. Key Features
- Precision Threading: Rolled threads with Class 6g tolerance ensure smooth engagement with standard M6 nuts and tapped holes.
- Corrosion Resistance: Available in zinc-plated, hot-dip galvanized, or A2/A4 stainless steel finishes for harsh environments.
- Full Shank Design: The 60mm length provides maximum shear strength across the entire unthreaded portion.
- Hex Head Profile: Standard 10mm across-flats (AF) head allows compatibility with common sockets and wrenches.
- Load Capacity: Property class 8.8 (carbon steel) offers 800 MPa tensile strength; stainless A2-70 provides 700 MPa.
- Consistent Dimensions: Thread run-out controlled to within 2.5 threads from head for reliable clamping.

4. Application Scenarios
The m6 x 60mm hex bolt serves critical roles across multiple industries:
- Automotive Assembly: Securing engine brackets, suspension components, and exhaust heat shields where 60mm reach is required to pass through bushings.
- Industrial Machinery: Mounting motor bases, conveyor belt guides, and guard rails on steel frames.
- Construction: Fixing steel beams to concrete anchors via M6 threaded rods; attaching handrail brackets.
- Electrical Enclosures: Fastening cable tray supports and junction box covers in electrical cabinets.
- Furniture Manufacturing: Heavy-duty office chair bases and workbench leg connections.
5. Advantages
Choosing the m6 x 60mm hex bolt over generic fasteners provides measurable benefits:
- Optimized Grip Range: The 60mm length bridges gaps up to 30mm (with nut/washer), reducing the need for shims.
- Reduced Rework: Consistent thread geometry prevents cross-threading during high-speed pneumatic tool assembly.
- Longevity: Zinc-nickel plating offers 500+ hours salt spray resistance (ASTM B117).
- Weight Efficiency: M6 shank diameter saves 40% weight vs M8 bolts while maintaining adequate strength for medium loads.
- Global Compliance: Meets DIN 933, ISO 4014, and GB/T 5783 standards for international shipping.

7. FAQ
Q: What is the exact thread length on this M6 x 60mm hex bolt?
A: Our standard DIN 933 version has full threads (60mm length). For DIN 931 partial thread, the thread length is 18mm with a 42mm plain shank. Please specify when ordering.
Q: Can these bolts withstand outdoor marine environments?
A: Yes. We recommend A4 (316) stainless steel grade for coastal installations. Our standard zinc plating is suitable for indoor/covered outdoor use only.
Q: What torque should I apply for Class 8.8 M6 bolts?
A: Recommended tightening torque is 8-10 Nm (dry) or 6-8 Nm (lubricated) for optimal preload. Always verify with a torque wrench on critical joints.
Q: Do you offer these bolts with nylon patch locking?
A: Yes, we can apply a nylon patch (vibration-resistant) to the threads for an additional fee. Minimum order quantity applies.
Q: What is the packaging weight for 1,000 pieces?
A: Approximately 8.5 kg (including box). Each M6 x 60mm hex bolt weighs roughly 8.2 grams. We can consolidate with other fasteners for shipping efficiency.
