Two-Sided Bolt
Products Description
A two-sided bolt is a fastener with threads on both ends and a bolt-like body. It is commonly used in applications requiring bidirectional connections, structural extension, pre-tightening, and the ability to withstand continuous loads. Compared to traditional bolts, it is suitable for more complex and multi-angle installation environments, making it a key standard component in industrial equipment that combines long-term stability, strength, and ease of maintenance.
Core Values:
High coaxiality and balanced force distribution
Suitable for deep holes, narrow spaces, and double-ended fixing structures
Improves assembly efficiency and maintenance flexibility
Supports customization of various materials, lengths, thread profiles, and surface treatments
Key Features Overview
Double-Ended Thread Design
Offers standard equal-length and unequal-length Double Ended Carriage Bolts. The unequal-length design allows for a shorter engagement length at the screw-in end for permanent installation, while the nut end retains a longer length to accommodate thicker connectors.
Differentiated Thread Configurations
Different thread pitches and precision grades can be used at both ends to accommodate different base materials and connection requirements.
Smooth Shaft with No Thread
Some specifications feature a precise, smooth shaft section for accurate alignment or as a shear surface to withstand lateral loads, functionally surpassing ordinary fasteners.
Full Material Coverage
Offers a complete material system from high-strength carbon steel and stainless steel to heat-resistant alloy steel, meeting comprehensive needs from room temperature to high temperature and from general corrosive to highly corrosive environments.
Manufacturing Advantages: A Perfect Blend of Precision and Efficiency
Intelligent Precision Manufacturing Process
We employ advanced intelligent manufacturing systems to achieve end-to-end digital management from design to production. AI-assisted design ensures all key factors are considered during Double Threaded Bolt development, while intelligent production lines ensure every product meets the highest standards. An intelligent quality control system monitors key parameters in real time during manufacturing, ensuring consistent product performance and reliability.
High-Precision CNC Machining Technology
The manufacture of Double-Ended Threaded Bars utilizes high-precision CNC machining technology, ensuring each dimension is accurate to the micron level. Precision turning and rolling processes ensure smooth, burr-free threads, avoiding surface defects common in traditional machining. This precision machining allows the screws to maintain structural integrity over long-term use.
Efficient Mass Production
Our optimized manufacturing processes enable efficient mass production. Through automated production lines and intelligent scheduling systems, we ensure a stable supply of high-quality products to meet the needs of large-scale industrial applications while reducing unit costs.
Detail Showcase
Thread End Shape
Both ends of the thread undergo fine chamfering to create a smooth guide surface, ensuring the stud can be easily and effortlessly screwed into the base and nut.
01
Smooth Shaft Surface Finish
The smooth shaft portion, serving as the positioning surface, undergoes fine grinding or polishing to achieve a mirror or high-gloss finish, ensuring a precise fit and smooth sliding.
02
Material Identification
The material grade, strength class, and batch number are clearly and permanently marked on the end face or smooth shaft portion of the stud using steel stamping or laser engraving, enabling full quality traceability from finished Double Point Screw to raw material.
03
Surface Treatment Effect
The Dacromet coating presents a uniform silver-gray color, with no missed areas or runs; the stainless steel passivation surface is clean and free of acid stains, demonstrating excellent process control.
