Stainless Steel Unequal Double-End Studs
product detail
Description of Stainless Steel Unequal Double-End Studs
Unequal double-end studs (also known as unequal-length double-ended bolts or double-ended screws) are fasteners with external threads at both ends but different lengths, with a smooth spool or special structure in the middle, connected by a nut for tightening. The main difference between them and equal-length studs is the difference in length between the long and short ends, allowing for precise matching of the thickness differences between the two connecting parts, avoiding material waste or problems with the nut not being able to screw in.
Made entirely of high-quality stainless steel (304/316), they possess excellent corrosion resistance and oxidation resistance, suitable for humid, chemical, and outdoor environments. The products conform to standards such as GB897/GB899 and DIN835. The short thread end is typically 1 or 1.5 times the thread diameter, and various specifications are available.

Quality Inspection
Why choose us?
1.Experience
As a manufacturer specializing in stainless steel unequal-length double-ended studs for over ten years, we are proficient in hot rolling, cold heading, and thread rolling processes. From the length ratio of the short thread end to the thread profile accuracy of the long thread end, every process has standardized quality inspection procedures. Customers trust us because we understand materials, standards (GB/DIN/ANSI), and, most importantly, your equipment connection needs.
2.Customization
Not limited to standard specifications. We support customization of diameter, thread length ratio, material (304/316/carbon steel), and surface treatment, and offer free samples. As a one-stop bolt supplier, we transform non-standard into mass-producible, making the "unequal length" requirement of special sizes no longer a procurement challenge.
3.Scale
Multiple CNC lathes, thread rolling machines, and heat treatment equipment enable a daily production capacity of tens of thousands of pieces. We maintain a large inventory of commonly used specifications, and support same-day shipping for urgent orders. Due to direct sourcing, our double-ended stud prices are more competitive than those of intermediaries—larger quantities receive even better prices, with no hidden costs.
4.Service
A professional after-sales team provides full support, from product selection advice to installation torque guidance, offering long-term technical support. We don't just sell products; we provide fastening and connection solutions. Choosing us means choosing a worry-free, reliable, long-term partner.
Production Process
Application of Stainless Steel Unequal Double-End Studs
Stainless steel unequal-length double-ended studs are widely used in equipment assembly scenarios requiring unilateral installation but with significant connection thickness. The shorter threaded end screws into thick-walled workpieces or blind holes for fixation, while the longer threaded end protrudes to engage with a nut and secure other components. They are commonly used in chemical pressure vessels, oil pipeline flange connections, ship bulkhead penetrations, and internal structural fastening in mining machinery and metallurgical equipment. Choosing a professional double-ended stud manufacturer ensures that thread accuracy and mechanical properties meet GB/DIN/ANSI standards. As a reliable fastener supplier, we offer 304/316 stainless steel materials and custom services for non-standard thread lengths. Direct manufacturing gives us a price advantage. The stainless steel material is corrosion-resistant and rust-resistant, suitable for humid, acidic, alkaline, and outdoor environments, ensuring long-term stable and reliable connections.
