Seegers, self-locking nuts, threaded inserts, and small metal parts

BULL-VIT's range of technical fasteners includes a comprehensive selection of essential components for assembly and fastening in industrial and agricultural applications. Each category is designed to meet high standards of durability, precision, and compliance with international regulations, ensuring reliability in demanding environments.

Screws for agricultural machinery

Screws designed for the agricultural sector are characterized by high mechanical strength, making them ideal for withstanding vibrations, impacts, and heavy loads. Manufactured from high-strength steels such as grade 8.8, these screws comply with UNI EN ISO 898-1 specifications to guarantee certified operational safety.

Spring and cylindrical pins

Spring pins, compliant with UNI 6873 and DIN 1481 standards, and cylindrical pins, manufactured according to DIN 7, are used for precise positioning and force transmission in mechanical assemblies. Available in untreated and hardened steel, they offer excellent wear resistance and easy installation.

Parallel keys

Manufactured from C45 steel, parallel keys comply with UNI 6604 and DIN 6885 standards. These components ensure a secure connection between shafts and hubs, guaranteeing stable power transmission.

Lifting eye bolts and nuts

Eye bolts (male or female) facilitate load lifting and anchoring operations. The circular eye bolts supplied by BULL-VIT comply with UNI 2947 and UNI 2948 standards. Available in galvanized steel and A2 stainless steel, they are designed for safe lifting applications, maintaining reliability even in corrosive environments.

Snap pins

Snap pins serve as safety fasteners to reinforce assemblies. Manufactured according to UNI 1336 and ISO 1234 standards, these zinc-plated steel components offer a cost-effective solution for securing pins and mobile assemblies.

Retaining rings (Seeger rings)

Seeger rings, for both internal and external applications, meet UNI 7435 and UNI 7437 standards and are made of harmonic steel. These components ensure a secure hold on shafts or bores, even under dynamic loads.

Self-locking nuts

Self-locking nuts provide anti-loosening functionality under vibration and load conditions. BULL-VIT supplies standard series GUK self-locking nuts, which ensure a secure grip thanks to an integrated nylon ring. These are ideal for high-performance mechanical applications.

Threaded inserts

Threaded inserts allow fastening in applications where machining internal threads is not feasible. The FTR and FTT inserts, made of zinc-plated steel, provide excellent torsional resistance and are designed for materials such as wood or plastic, meeting ISO metric thread requirements.

Blind rivets

Blind rivets are used in applications where installation is only possible from one side, hence their name. The aluminum alloy rivets, with a steel shaft, are available in both untreated and white zinc-plated versions. Designed for fast installation, they comply with standards for tensile and shear strength.

Hex keys

Hex keys (also known as Allen keys) are mechanical tools with a hexagonal cross-section. The RS160 hex keys, conforming to UNI 6753 standards, are made of ultra-high-strength steel, ensuring durability and precision even in demanding operational conditions.
