4. Stainless Steel Bolts
These bolts are forged on heavy upsetting machines and are then machined on latest CNC machines in our factory.
These Stainless steel bolts in bigger diameters are 100% thread rolled using imported thread rolling machines from ORT Italy and HMT Praga in India. We are the only company in India which does thread rolling on stainless steel bolts from M-20 diameter to M-52 diameter.
Stainless steel hex bolts or screws are offered in A4-70, A4-80, B8, B8M Class 1 and class 2, and in SS316S31 grades. We also offer these grades in 316 and 316L grade. The difference between 316 and 316L is simply the limit of carbon content to 0.03% maximum in 316L grade, whereas in 316 grade it is limited to 0.08%.
Stainless steel bolts provide a strong and a longer life where specific requirement of rust prevention is predominant. Predominantly stainless steel bolts are used in areas where there is a high risk of corrosion, this can be in TSE networks, affluent treatment plants, water pipe lines, pumping stations or in mega reservoirs. Stainless steel bolts provide high resistance to corrosion and normal wear and tear over the years.

Stainless steel bolts are used in underwater projects where there is direct contact with sea water, in drainage systems, affluent treatment plants, TSE networks, Pumping stations, desalination plants and various other sectors as.

6. T-Bolts
We can offer surface finishing as per customer requirement in hot dip galvanising, we take special care to ensure there is no hydrogen embrittlement in 10.9 grade with our special curing system which ensures that 10.9 grade bolts are not damaged by hydrogen embrittlement post galvanising process. We also do zinc electroplated in blue, yellow or black colour as per customer requirements.
Black oxide or black coating is a general type of coating offered on bolts & nuts & stud bolts to give a pleasant appearance and to prevent any rusting during transportation or storage, the normal salt spray life for the fasteners applied with such coatings is often less than 100 hours

7. 12-point-bolts
Understanding 12-Point Bolt
The distinguishing characteristic of 12-point bolts, frequently referred to as 12-point flange bolts, is the star-shaped head design with twelve points. In comparison to conventional hex bolts, this design enables greater torque capacity and superior resistance to head shearing. The flange, which offers a larger bearing surface, distributes the clamping force equally, thus offering greater resilience.
Key Advantages:
Higher Torque Capacity:
With twelve points, the wrench has a larger contact area, allowing the bolt to withstand more torque without damage.
Improved Stripping Resistance:
The distinctive head design decreases the possibility of stripping, especially under high torque or vibration conditions.
Ease of Installation:
The head design allows for access from any angle using a normal wrench, making installation and removal easier in tight areas.
Versatile Use Cases
12-point bolts are essential in several industries because of their strength and dependability:
Oil and Gas:
Due to the severe conditions and high-stress situations in the oil and gas industry, 12-point bolts are crucial for assuring the robust and reliable fastening of critical components such as pipelines, machinery, and infrastructure.
Mining and agriculture:
In these industries, where heavy gear operates in tough and abrasive environments, 12-point bolts provide the endurance and strength required to ensure equipment integrity and lifetime.
Construction: Projects in the construction industry frequently demand high-strength fasteners for heavy-duty applications. 12-point bolts are perfect for anchoring structural parts, machinery, and equipment, providing stability and dependability in construction and infrastructure projects.
Transportation:
12-point bolts are especially beneficial for vehicles that are subjected to high levels of vibration and mechanical stress. They ensure secure connections in critical components such as engines, suspension systems, and chassis, which improves safety and performance.
Bolt Grade Comparison: What to Choose?
Selecting the right 12-point bolt grade is crucial:
Grade 8 and 9 A574:
These grades are appropriate for automotive, aerospace, and heavy machinery applications due to their high tensile strength and fatigue resistance.
Grade 10.9:
Construction and industry employ this extremely strong steel grade for its durability and load-bearing capabilities. For harsh and strong applications, it’s preferred.
Grade 12.9:
The strongest standard bolt grade, Grade 12.9, is utilised in aerospace, military, and high-performance engineering. They withstand great stress and operate well in the toughest conditions.
Quality Standardisation: DIN vs. ISO
DIN and ISO establish 12-point bolt guidelines:
Thread Form:
ISO standards employ metric threads for global compatibility and interchangeability. Besides metric threads, DIN standards offer unified threads and other alternatives, making them versatile for diverse applications.
Strength Rankings:
DIN fasteners frequently outperform ISO fasteners in strength. This makes them appropriate for high-load-bearing and durable applications.
Material and Size Specifications:
DIN standards address more sizes, materials, and mechanical qualities in depth. This detailed guidance helps engineers and designers choose the right fasteners for their purposes.
