¿Qué son los tornillos de hombro y para qué se utilizan?

Los tornillos de hombro, también conocidos como pernos de hombro, son tornillos para máquinas con un hombro cilíndrico no roscado de mayores dimensiones que las roscas. Al proporcionar una superficie de apoyo lisa, el hombro permite que el tornillo gire las piezas. Suele tener una cabeza ranurada o embutida y un hombro moleteado o plano. Ofrecen una mayor precisión y repetibilidad y, normalmente, son más fiables que otros tipos de fijaciones.

Lo que hace que los tornillos de hombro sean diferentes a otros tipos de tornillos es que están diseñados para su uso en piezas que requieren un pasador de montaje, una junta, un pivote o un movimiento deslizante en particular.

Aplicaciones de los tornillos de hombro

Los tornillos de hombro también se utilizan en aplicaciones en las que se necesita un ajuste a presión, como en el montaje de un motor o un accionador, y son ideales para aplicaciones que requieren un alto grado de resistencia a la vibración y fuerza. Entre estas aplicaciones se incluyen el acoplamiento de piezas en máquinas, la sujeción de componentes y la colocación de piezas.

Shoulder Screws - Hex Socket Head

En stock En producción

These Shoulder Screws, also known as shoulder bolts, are a type of fastener with a cylindrical shoulder that separates the screw's head from its threaded part. The shoulder is machined to a precise tolerance and serves as a bearing surface for the screw head.

Shoulder Screws are useful in situations that call for a mounting pin, dowel, joint, shaft, or sliding action. It is somewhat magnetic, strong, and corrosion resistant, but not in very harsh conditions.

This range of Shoulder Screws features a hexagonal socket head, which allows them to be easily tightened or loosened with an Allen wrench or hex key. They also feature a non-smooth head, which aids in gripping. These screws are suitable for electronics, machinery and automotive applications.

  • Shoulder is machined to a precise tolerance and serves as a bearing surface for the screw head.
  • Easily tightened or loosened with an Allen wrench or hex key.
  • It is somewhat magnetic, strong, and corrosion resistant.
Material: Stainless Steel, Black Steel

Shoulder Screws - Pan Head

En stock En producción

These Pan Head Shoulder Screws, also known as pan head shoulder bolts, are a type of fastener that consists of a cylindrical shaft with a pan head at one end and a shoulder at the other. The shoulder is machined to a precise tolerance and serves as a bearing surface for the screw head.

Shoulder Screws are useful when a mounting pin, dowel, joint, shaft, or sliding motion is required. It is sturdy and corrosion-resistant, but not in really hard conditions.

This range of Shoulder Screws features a pan head that is slightly domed and a flat bearing. It is suited for low-profile applications and has an aesthetically attractive appearance. Easy to install or remove using slotted screwdrivers. These screws suit electronics, medical devices, machinery and automotive applications.

Shoulder Screws - Slot Head

En stock En producción

These Shoulder Screws, often known as shoulder bolts, are a kind of fastener having a cylindrical head and a threaded shank. They feature a shoulder that runs from the head to the shank which is machined to a precise tolerance. Shoulder screws are commonly used to connect two components, with the shoulder acting as a bearing surface.

Shoulder Screws are appropriate for applications requiring a mounting pin, dowel, joint, shaft, or sliding motion.

This range of Shoulder Screws features a slotted head, which allows them to be driven with a slotted screwdriver. They are magnetic and have excellent shear resistance, although they corrode somewhat more easily than conventional shoulder screws. These screws are suitable for electronics, machinery, automotive and construction applications.

Shoulder Screws - Cap Head

En stock En producción

This range of Shoulder Screws feature a cap head with a choice of hexagonal , torx or slotted drive.

  • Hexagonal drives are ideal for precision assembly and are ideally used where less surface area is available.
  • Torx drives provide a positive-engaging, fast-locating technique for transmitting drive torque with less necessary downward pressure.
  • Slotted drives accept standard blade screwdrivers and require less downward pressure to drive parts, than those with recessed openings.

They are made from austenitic Stainless Steel or Titanium that provides good resistance to corrosion and machinability. The material is a popular choice for construction and automotive applications.

  • Material: Stainless Steel, Titanium G5
  • AISI 303, 1, 4305
  • Tensile Strength: 550 N/mm²
  • Proof Stress Minimum: 190 N/mm²

Vented Shoulder Screws - Cap Head

En stock En producción

Vented screws are fasteners with a hole drilled through the middle that allow gases trapped at the bottom of a blind threaded hole to escape through the core and provide airflow within an application. The screws are a common option for HV and UHV systems because their centre vent feature reduces virtual leakage from high vacuum systems.

This range of Vented Shoulder Screws features a cap head with a hexagonal drive. Hexagonal drives are suitable for precision assembling and when there is limited surface area and the precision shoulder allows accurate assembly. They are made from Stainless Steel.

  • Material: Stainless Steel
  • AISI 304, 1.4301
  • Strength Class: 50
