About Half Threaded Bolt
It is made in the smooth unthreaded shank with threaded end having good shear strength and dependable clamping effectiveness. The design is properly aligned, evenly loaded, and has enhanced structural integrity. These bolts are usually used in machinery and in automotive systems and assemblies that are heavy and demand very high degree of accuracy and durability.
Types of Half Threaded Bolt
As reputed Half Threaded Bolt manufacturers in Germany, we supply a focused range of bolts built for accurate alignment.
- Hex Head Bolts (DIN 931): They are the most popular half-threaded bolts that have a powerful hexagonal head to be used in high torque. They provide high shear strength in ensuring that they suit machinery, automotive components, and general structural assemblies.
- Hex Socket (Allen) Bolts: These bolts are internal drive designed bolts that can fit into smaller or limited areas that a normal wrench is unable to reach. They have clean result and tightening joints and dependability in accuracy machines.
- Flange Bolts: The bolts have a flange built into the head that permits the distribution of loads over a wider area and reduces the necessity of an independent washer. They are usually applied in automobile frames, engines and equipment where constant clamping is essential.
- Rag Bolts / Foundation Bolts: These bolts are designed to attach anchoring structures into concrete or masonry walls, and have rounded or modified ends to provide a better grip. They are also needed in heavy foundations, industrial installations and structural supports.
- Mild Steel (MS): These are cheap and can be used in normal applications that do not demand high strength. To enhance the durability and general environmental resistance to corrosion they are galvanized or coated.
- Stainless Steel (SS): These bolts particularly SS 304 and SS 316 have high degrees of resistance to corrosion in marine, chemical, and outdoor settings. They are long-life performance with rust prevention being of crucial importance.
- Alloy Steel: These bolts in 8.8 and 10.9 grades are applied in high tensile strength in structural and heavy load structural applications. They are applicable in situations where high toughness, reliability and safety requirements are needed.

Benefits of Half Threaded Bolt
As leading Half Threaded Bolt traders in Germany, our bolts deliver strong holding power, long service life, and dependable fastening.
- Superior Shear Strength: The unthreaded shank has a better retention of the lateral forces and therefore the bolt is capable of being subjected to greater shear loads. This makes the concentration of stress minimal and structural interconnections more stable.
- Accurate Alignment & Faster Assembly: The shank is smooth, which allows the components to simply fit into position during tightening to install more quickly and accurately. This guarantees efficient machinery and construction assembly will be cleaner.
- Reduced Stress & Improved Fatigue Life: The bolt reduces the stress build-up in local areas by dividing the shear on the shank and tension on the threads. Such design increases fatigue resistance particularly when repeated or cyclic loads are taken.
- Versatile for Mixed Load Applications: These bolts have been useful in places where the tension and shear forces can occur. Their symmetrical form allows its use on heavy equipment’s, structural frames and machinery components.
- Lower Galling Risk & Cost Efficiency: Less thread involvement at the beginning of the assembly process leads to fewer possibilities of galling or seizing during the assembly process. Partial threading will also be cost saving as less machining will be required.
Applications of Half Threaded Bolt
As notable Half Threaded Bolt dealers in Germany, our bolts are used in machinery assemblies, structural frameworks, and industrial equipment.
- Heavy Machinery & Equipment: Half-threaded bolts have good shear strength and vibration damping that allows one to mount pumps and compressors and other load-carrying components in high-stress machinery.
- Construction and Structural Frameworks: They provide the accuracy of positioning and form stable joints between beams, columns, and industrial structures and are effective in managing shear and tension forces.
- Petrochemical and Pipeline Systems: These are the bolts that distribute loads equally in flange assembly and pipeline supports, which guarantee safe and reliable performance at high pressure and at temperatures of thermal expansion.
- Automotive Assemblies: Partial threading improves the process of load transfer and minimizes wear in engine mounts, alternators and any parts subjected to vibration on a regular basis.
- General Industrial Applications: They provide correct guidance and steady operation of equipment groups that face vibration, movement, or unequal loading provisions.
