DIN 960 Hex Head Bolts -Ravina Fasteners

DIN 960 Hex Head Bolts are precision-engineered fasteners featuring a fine-pitch metric thread and a partially threaded shank, ideal for applications requiring enhanced strength, accuracy, and vibration resistance. Manufactured in accordance with German DIN standards, these bolts are widely used in automotive, aerospace, machinery, and heavy equipment industries.

The hexagonal head design allows for easy tightening using standard tools, while the fine thread offers better clamping force and greater fatigue resistance compared to coarse threads. Available in various materials and finishes, including high-tensile steel and stainless steel, DIN 960 bolts from Ravina Fasteners ensure reliable performance in both static and dynamic applications.

Overview of DIN 960 Fine Thread Hex Bolts

DIN 960 Hex Head Bolts

are precision mechanical fasteners designed with a fine-pitch thread and partial threading, making them ideal for applications that demand enhanced tensile strength, vibration resistance, and accurate alignment. Unlike fully threaded bolts, the partially threaded shank improves shear strength and clamping performance, especially in high-stress or dynamic environments.

These bolts conform to German DIN 960 standards and are widely used in automotive assemblies, heavy machinery, industrial equipment, and aerospace structures. The fine thread allows for tighter tolerances, smoother adjustments, and reduced loosening under vibration—a key benefit over standard coarse-thread bolts.

Manufactured from high-grade materials like carbon steel, alloy steel, and stainless steel, and available with surface treatments such as zinc plating, hot-dip galvanizing, or black oxide, DIN 960 bolts offer durability, corrosion resistance, and reliability across diverse operating conditions.

Key Features of DIN 960 Bolts

DIN 960 Hex Head Bolts are manufactured in a range of mechanical property classes (grades) to meet specific application demands. These grades define the bolt’s tensile strength, yield strength, and hardness, making it easier to select the right bolt for structural integrity and safety.

Metric Fine Thread Details

DIN 960 bolts feature metric fine pitch threads, which differ from standard (coarse) threads by having smaller pitch distances — the distance between adjacent threads. Fine threads offer numerous advantages in precision engineering and high-performance applications.

Advantages of Fine Threads in DIN 960 Bolts:

• Higher Tensile Strength – More threads per unit length distribute stress more evenly.

• Better Vibration Resistance – Less likely to loosen in dynamic environments.

• Improved Adjustability – Enables finer torque control in precision applications.

• Enhanced Load Holding – Ideal for thin-walled materials or assemblies needing strong clamping force.

All bolts conform to DIN 960 standards as defined by DIN Deutsches Institut für Normung.
