Stainless Steel Stamped Pin, Cold Forged Adjustment Pin, Custom Eye Terminal Crimp Pin Mechanical Hardware Parts
Situo Hardware is a professional custom manufacturer specializing in stainless steel stamped pins, cold forged adjustment pins, eye terminal connecting pins, non-standard ring terminal fasteners, and composite process positioning pins. Our products are widely applied in electrical wiring, cable terminal connection, automation equipment adjustment mechanisms, tooling fixture positioning, mechanical hinge assembly, and new energy equipment supporting fields.
This series of stainless steel eye terminal pins adopts a composite manufacturing process. The main pin body is integrally cold forged with continuous metal grain flow, ensuring excellent tensile strength, shear resistance and structural toughness. The eye terminal (ring terminal) part is precision stamped with flat surface, standard inner aperture and no deformation. Integrating adjustment, positioning, hinge connection and terminal fixing functions, it serves as both a fine-tuning limit pin and a special connecting pin for cable eye terminals. Full non-standard customization is available for pin diameter, total length, eye hole size, ring thickness, step limit and offset structure, meeting diverse assembly needs of equipment fine adjustment, cable terminal fixing and mechanical movable connection.
Factory Technology & Core Advantages
1. Composite Forming Process: Cold Forging + Precision Stamping
The pin body and head are integrally extruded by cold forging dies with uninterrupted metal grain, featuring better fatigue resistance, vibration resistance and shear strength than fully turned pins, suitable for long-term reciprocating adjustment and hinge operation. The eye terminal is precision stamped with smooth flat surface, burr-free inner hole and high roundness, perfectly matching standard eye terminals and crimp terminals for cable assembly.
2. Premium Stainless Steel Material with Durable Rust Resistance
Optional 201, 304, 316 stainless steel provides excellent corrosion and oxidation resistance. No rust or jamming occurs in humid, outdoor and electrical working environments, ensuring stable performance for long-term service.
3. 3-in-1 Multi-Functional Design
Different from ordinary single-function pins, this product integrates adjustment, positioning and terminal connection functions. It acts as an adjustment pin for stroke and gap fine-tuning, a locating pin for tooling alignment, and a professional fastener for fixing cable eye terminals, simplifying equipment structure and improving assembly efficiency.
4. Flexible Full-Parameter Non-Standard Customization
Customizable specifications: pin diameter, overall length, threaded adjustment section, limit step, eye hole diameter, ring outer diameter and thickness. Secondary processing such as slotting, flat milling and anti-rotation groove is supported. Solid and semi-hollow structures are available. We accept custom orders per drawings and samples, supporting sampling, small-batch trial and mass production.
5. Fine Surface Treatment for Smooth Assembly
Standard passivation and vibratory deburring remove sharp edges and burrs. Optional polishing, nickel plating and zinc plating deliver high surface smoothness. The inner wall of the eye terminal will not scratch cables during assembly, and the pin body slides smoothly without jamming or wear.
6. Strict Quality Control System
Complete inspection procedures include raw material verification, cold forging blank screening, eye terminal roundness test, hole gauge inspection, straightness detection and appearance trimming. Key dimensions are precisely measured to ensure high batch consistency, meeting export quality standards for automation and electrical equipment accessories.
