Anchor Spade Bolt Bracket is a high-strength fastener assembly designed for power facilities, steel structure connections and heavy equipment fixation. Its unique spade-shaped base and bolt integrated structure can effectively disperse the load pressure and enhance the anchoring stability. It is suitable for high-voltage transmission towers, substation supports, bridge projects and industrial equipment foundation fixation. Handan Jinmai Fastener Manufacturing Co., Ltd. adopts advanced production technology to ensure that the product can still maintain excellent tensile strength and corrosion resistance in extreme environments, meeting the stringent requirements of global customers for safety and durability.
High-strength material
Select high-quality carbon steel or alloy steel (optional galvanized/Dacromet coating), with a tensile strength of 8.8 or above, suitable for high-load conditions.
Anti-corrosion design
The surface is hot-dip galvanized, electroplated or environmentally friendly Dacromet treated, with excellent salt spray corrosion resistance, suitable for humid environments such as coastal areas and chemical plants.
Structural optimization
The spade-shaped base expands the contact area and reduces foundation stress concentration; the bolt thread is precisely formed to ensure the tightness of the bite with the nut.
Convenient installation
The pre-set installation hole design supports rapid positioning and fixing, reducing the complexity of construction.
Customized service
Personalized solutions with non-standard sizes, special coatings or materials (such as stainless steel) can be provided according to customer needs.
Material selection
Steel that meets international standards such as ASTM and GB is used, and spectral testing is performed to ensure that the composition meets the standards.
Precision machining
The bolt head is cold-forged by CNC machine tools, and the spade-shaped base is integrated by stamping and welding processes, with an error control of ±0.1mm.
Surface treatment
After multi-stage cleaning, the anti-corrosion coating is completed using an automated galvanizing line or Dacromet spraying equipment, and the thickness uniformity reaches the highest industry standards.
Quality inspection
Hardness tests, torque tests and salt spray tests are performed piece by piece to ensure that the mechanical properties and anti-corrosion levels of the products meet ISO 898-1 and other specifications.
Packaging, storage and transportation
Anti-rust paper + wooden box/pallet packaging, with clear specification markings, supports moisture-proof requirements for sea transportation.
