Adjustable Anchor Screw

↵

Carbon steel galvanized external hexagon adjustable anchor screws (adjustable anchor screws) are high-performance fasteners designed to provide precise leveling and stable support for industrial equipment. With a spherical base structure, this unique design allows the equipment to remain absolutely level under different ground conditions, ensuring the stability and accuracy of the equipment's operation.

The main body of the product is made of high-quality carbon steel and is formed by a precision cold heading process to ensure the mechanical strength and durability of the screw. The surface is galvanized to create a uniform and dense protective layer, which significantly improves the corrosion resistance of the product. This double protection enables our anchor screws to maintain their functional integrity for a long time in humid, dusty, and even chemically corrosive environments, thereby extending the service life of the equipment.

The adjustable anchor screws are made of high-quality carbon steel and are specially processed. A single M8 specification screw can withstand a vertical load of up to 9,000 pounds. This ultra-high load capacity ensures that even the heaviest industrial equipment can be firmly supported. The internal grain structure of the screw is optimized to effectively disperse stress when subjected to heavy loads to prevent local deformation or breakage.

The external hexagonal head also adopts a thickened design, which not only facilitates the application of greater torque during installation but also effectively prevents the wear of corners caused by tool slippage. The arc transition structure is used at the junction of the hexagonal head and the screw, which improves the overall structural strength and fatigue life of the screw. The product also adopts a trapezoidal thread design, which has a larger load contact area and a flatter stress distribution than the traditional V-thread.

All-round adjustment capability

The anchor screw adopts a spherical base design, which allows the bolt to rotate freely relative to the base. This design effectively solves the problem of equipment tilting caused by uneven ground and ensures that the equipment remains perfectly level under various ground conditions. The screw adopts a precision thread match, and the M6 ​​specification can achieve 1.25 mm precise height adjustment per rotation. This fine-tuning capability is essential for the calibration of precision instruments, optical equipment, or production lines that require high-precision positioning.

The external hexagonal head design is compatible with standard hand tools and pneumatic/electric tools, and the installation and adjustment efficiency is increased by more than 50%. An adjustment handwheel can also be installed on the top of the screw to make frequent adjustments more convenient, especially suitable for workshop environments where the position of equipment needs to be adjusted at any time according to production needs.

Durability and corrosion resistance

The surface of the screw is galvanized, and the surface of the zinc layer is color passivated to form an additional protective film to further improve the corrosion resistance. The salt spray test time can reach more than 200 hours to effectively prevent the equipment from sliding, while reducing more than 80% of vibration transmission. Significantly improve the operation accuracy and service life of the equipment.

Thanks to high-quality materials and advanced surface treatment technology, our anchor screws have a service life of more than 25 years under normal use conditions. The product has been tested for accelerated aging and verified under actual working conditions to ensure that the functional integrity and structural reliability are maintained throughout the life cycle. This long-life design reduces the frequency of equipment maintenance and replacement costs, providing users with long-term and stable support services.

Multifunctional design and wide applicability
Modular combination design: The product adopts a modular structure, and the screw, base, and anti-slip pad can be replaced or customized separately, which greatly improves the flexibility and economy of the application. Users can combine different components according to different equipment requirements. For example, heavy equipment can choose a large-diameter base and a high-load screw, while precision instruments can choose a shockproof base and a fine-adjustment screw.

Compatible with multiple specifications: We provide three mainstream specifications of M5, M6, and M8, covering most industrial application scenarios. Each specification has a variety of thread lengths to meet different height adjustment requirements. The base diameter is available in a variety of specifications from 40mm to 150mm, providing a suitable support area for the equipment to prevent the ground from sinking or deforming.

Application field

Our carbon steel galvanized hexagon adjustable anchor screws are widely used in multiple industries due to their excellent performance and reliable quality.

Industrial equipment and heavy machinery: In various machine tool equipment, injection molding machinery, stamping equipment, and other heavy equipment fields, our products provide stable support and precise leveling capabilities. Especially for large assembly lines, automated production systems and other scenes that require precise alignment, our adjustable anchor screws can easily achieve millimeter-level precision adjustment, significantly improving production efficiency and product quality.

Medical and laboratory equipment: CT scanners, MRI equipment, precision microscopes, etc., have extremely high requirements for vibration-free and absolute levels. Our stainless steel series anchor screws provide sanitary surfaces and micro-vibration isolation functions to ensure clear imaging and accurate detection of equipment. The surface of the product has been specially polished to meet the cleaning and disinfection requirements of medical equipment, effectively preventing bacteria from growing. At the same time, the fine adjustment function meets the needs of ultra-high precision equipment leveling, ensuring that the equipment maintains optimal performance during operation.

Communication and power equipment: It can provide a reliable grounding path, while the galvanized layer forms an electromagnetic shield to reduce signal interference. In response to the special needs of outdoor communication cabinets, we have developed reinforced anti-corrosion anchor screws with triple protective coatings, which can ensure long-term reliable operation even in harsh environments such as humidity and salt spray.

As a professional adjustable anchor screw factory supplier, we deeply understand the strict requirements of different industrial applications for equipment stability, so each screw is strictly quality controlled to ensure reliable support and long-term stable service for your equipment.
