Stud Bolt

Basic Info

A Stud Bolt is a fastener threaded on both ends,with either a plain shank or full thread(then often called a Threaded Rod).It is typically used with two nuts to join components with through-holes,especially suitable where one part is thick or requires frequent disassembly,such as flange connections or gear axial positioning.

Customer reviews

James Carter · Maintenance Engineering Supervisor

The Grade 10.9 high-strength bolts from your company were used in our steel structure platform. After two years of full-load operation, all connections remain completely tight with excellent torque retention. Such stability in a high-vibration environment demonstrates outstanding anti-loosening and fatigue resistance, helping us avoid costly downtime for maintenance.

David Müller · Procurement & Quality Manager

As a procurement party, we value consistent quality in bulk products the most. The Grade 8.6 hex head bolts we purchased from your company showed almost no deviation in mechanical performance tests (hardness, tensile strength) across five consecutive batches, with a 100% pass rate in thread gauge inspection. This consistency greatly ensures the efficiency and safety of our assembly line.

Dr. Emma Fischer · Chief R&D Engineer

"In the development of precision optical instruments, we have strict requirements for fastener dimensional tolerances and magnetic properties. The non-magnetic stainless steel miniature bolts (M1.6-M3) provided by your company fully meet the drawing tolerance requirement of ±0.015mm. Their vacuum degassing process effectively prevents contamination of the optical system by micro-gas emissions."

Product Description

Product Characteristics:

Key feature is symmetrical or asymmetrical threading on both ends,allowing installation/removal from either side for great flexibility.In flange connections,it withstands high axial tension and sealing pressure.Full-threaded rods allow nut placement anywhere as needed.High-grade studs ensure reliability under vibration and fluctuating loads.

Product Specifications:

Conforms to standards like ISO 4018,DIN 975(full thread),ANSI B16.5(for flanges).Diameters range from M6 to M64.Lengths vary widely from tens of millimeters to several meters(rod).Flange studs often have unequal thread lengths(short end screws into flange,long end for nuts).

Product Applications:

A critical fastener in petrochemical plants,pressure vessels,pipe flanges,valves,pumps,heavy machinery housings,mold installation,and curtain wall mullion hanging.Ideal for long-distance tensioning or where through-bolt access is limited.
