Product Description

PRODUCT PARAMETER

Fully threaded studs

Fully threaded studs are headless fasteners with threads along their entire length, designed for high-precision clamping and uniform load distribution. Unlike partial-thread studs, their continuous threading eliminates stress concentration, making them ideal for tensile-dominant applications. Materials include carbon steel (8.8/10.9 grade, zinc-plated), stainless steel (316 for corrosion resistance), and alloy steel. Standards like ISO 8734, DIN 975, and ASME B18.31.2 specify sizes from M6 to M100 and lengths up to 1,000mm. The full threading enables precise adjustment of nut position, enhancing preload consistency in critical connections.

Applications:

Pressure Vessels & Piping: Bolt flanged joints in boilers, reactors, or high-pressure systems (resists thermal expansion and leakage).
Heat Exchangers & Machinery: Secure tube sheets or covers in industrial equipment, ensuring uniform clamping force across surfaces.
Aerospace & Automotive: Join engine components or chassis parts that require repeated assembly/disassembly (threads prevent galling).
Electrical & Marine: Mount transformers or hull fixtures in corrosive environments (stainless variants resist saltwater/chemical damage).
Adjustable Frames: Assemble modular structures, conveyor systems, or scaffolding that demands fine-tuned positioning.
