Fasteners

Introducing continuously welded shear stud reinforcement manufactured by Ningbo Xinyi. This innovative product is designed to improve the strength and stability of shear walls in concrete engineering. The shear studs are continuously welded onto a steel plate rail, resulting in exceptional durability and structural performance. A variety of custom sizes are available to meet specific project requirements.

Grouted Rock Anchor is a specialized engineered anchoring system designed to provide high-strength holding capacity in challenging geological conditions. It is a 1.25-inch (31.7 mm) diameter, 3-foot (914 mm) long steel rod, specifically manufactured for situations where standard screw or wedge anchors are not feasible.

Expanding Socket Rock Anchor is a specialized foundation solution designed to secure guy wires for utility poles, transmission towers, and other structures in areas with solid rock formations. Instead of digging a large hole and pouring concrete, this anchor is installed directly into a drilled hole in the rock, using a mechanical expansion principle to achieve a high-strength hold.

Corner Attachment Bracket is a specialized hardware component used in overhead utility and communication line construction. Its primary function is to serve as a secure pole attachment point for terminating ("deadending") strands at specific angles.

The Climbing Cone Anchor System is a high-performance, reusable concrete anchoring solution designed for the safe and efficient attachment of climbing formwork systems in tall building construction.

The Spring Lock Washer, technically known as the Helical Spring Lock Washer within the standard, is a precision fastener component designed to prevent loosening of nuts and bolts under vibration, shock, and thermal cycling. Its effectiveness comes from two primary actions:

1. Spring Action: The washer acts as a compressed spring, maintaining a constant axial force (preload) on the bolted joint.

2. Biting Action: The sharp, hardened edges of the washer bite into the bearing surfaces of the fastener and the workpiece, resisting rotational loosening.

Product Overview

The Line Post Stud is a critical component in overhead power distribution systems, designed to securely mount post-type insulators onto utility poles or crossarms. Manufactured from high-strength steel and hot-dip galvanized for corrosion resistance, these studs ensure reliable electrical insulation and mechanical support in various environmental conditions.

Double Arming Bolt, commonly abbreviated as DA Bolt in the industry, is a heavy-duty fastener widely used in the construction of overhead power lines and communication lines. It is primarily applied to the double crossarm structure of utility poles, functioning to maintain spacing, transfer loads and stabilize the overall structure.

The DIN 931 standard specifies the technical delivery conditions for hexagon head bolts with a shank that is partially threaded. These are among the most common and widely recognized fastener types in the world, known for their reliability and strength. The "partially threaded" design provides a non-threaded bearing surface under the head, which offers higher shear strength and better alignment in bolted connections compared to fully threaded screws.

DIN 551 is a German industrial standard that specifies the dimensions, technical specifications, and testing requirements for slotted set screws with a flat point. This standard ensures interchangeability and consistent performance for these fasteners. The "flat point" (also known as a flat tip or flat end) is a key feature, designed for applications where the screw must press against a surface without marking it or where it needs to sit securely on a flat machined area.

Combination (Phil/Slot) Round Head Machine Screw

A versatile fastener featuring a round head with dual drive options (Phillips and slotted), designed for machine assembly applications requiring a smooth finish and moderate clamping force.

Definition: A split-type locking pin with extended prongs (legs) and a square-cut end profile, designed for secure fastening in high-vibration applications.
