Hemlok Structural Blind Rivet

Product Parameter

Unique Spline Locking Structural Advantages

The core competitiveness of Hemlok Structural Blind Rivet lies in the innovative spline mandrel locking and integrated expansion structure, which completely surpasses the performance limitations of ordinary blind rivets. During the riveting process, the rivet body expands evenly at the blind end to form a large-area stable supporting foot, which disperses the bearing pressure and avoids local stress concentration. The spline tooth groove design realizes full occlusion locking between the mandrel and the rivet tube. After pulling, the mandrel is completely fixed without shedding or loosening, eliminating hidden dangers such as equipment abnormal noise and circuit short circuit caused by mandrel falling off. In addition, the flexible expansion structure can compensate for assembly errors such as hole deviation, oversized holes and irregular hole shapes, ensuring tight and gap-free fastening of workpieces, with far higher structural stability than conventional rivets.

Graded Material Matching & Working Condition Adaptability

We provide multiple graded material combinations for hemlok rivets to meet differentiated load and environmental requirements. Aluminum-steel models feature light weight and moderate strength, suitable for general structural assembly with vibration resistance requirements. Full steel high-strength versions undergo professional heat treatment, with ultra-high tensile and shear resistance, perfectly matching heavy-load structural fastening scenarios such as new energy equipment and vehicle parts. The zinc-plated surface effectively isolates oxidation and atmospheric corrosion, maintaining long-term structural stability in indoor, outdoor and humid environments. All materials have excellent anti-fatigue performance, which can resist long-term cyclic vibration load without rivet loosening, dislocation or failure, meeting the high-reliability standards of structural engineering.

Precision Structural Forging & Strict Quality Control

All hemlock structural rivets are manufactured through integrated cold forging and precision tooth groove rolling technology. The rivet tube wall thickness is uniform, the expansion toughness is stable, and the spline mandrel tooth shape is complete and accurate, ensuring precise locking fit. The whole body has no burrs, cracks or dimensional deviations, with smooth surface and stable riveting stroke. Each batch of products undergoes professional mechanical performance tests, including tensile breaking test, shear strength test, vibration fatigue test and locking retention test. Strict dimensional tolerance control ensures consistent riveting effect and structural stability in batch assembly, supporting high-standard industrial mass production and engineering project procurement.

Professional Installation Process & Usage Guidelines

Hemlok structural rivets belong to high-standard structural fasteners, requiring professional pneumatic or hydraulic structural rivet tools for installation. Before construction, select the matching specification according to the actual workpiece thickness and load grade, and ensure the drilling hole diameter matches the rivet outer diameter. Keep the rivet vertical during riveting to ensure uniform expansion and complete locking of the blind end structure. This product is specially designed for high-strength, anti-vibration and error-tolerant assembly scenarios, and is the preferred fastener for structural parts that require long-term stable connection. It is not applicable for temporary low-load assembly. For key structural projects, batch sampling inspection is recommended after installation to verify fastening quality.

Structural Customization & Large-Volume Engineering Supply

We support personalized customization of hemlock structural rivets for special engineering and equipment matching needs. It can customize non-standard grip length, special head size and enhanced anti-corrosion models for extreme working conditions. All conventional structural specifications are in sufficient stock to support rapid sample delivery and large-scale project batch supply. Complete mechanical performance test reports and qualification documents can be provided to support project acceptance and foreign trade customs clearance. Equipped with export-grade moisture-proof packaging and OEM marking services, it has stable long-term supply capacity for new energy manufacturing, automotive supporting, rail transit and structural engineering industries.
