M12 bolts
M12 stainless steel bolts are one of our most popular fastening products, made from premium grades to ensure maximum strength and longevity. With their versatile 12mm thread diameter, these bolts offer an optimal balance of durability, performance and value. Our range of M12 bolts are precision engineered to meet DIN and ISO standards.
What size bolt is an M12 bolt?
An M12 bolt refers to a metric bolt with a thread diameter of 12 millimeters. This measurement is crucial for selecting the correct bolt for your specific application. It's important to ensure that the M12 bolt matches the corresponding thread size in your nuts, washers, or threaded holes to achieve a secure and reliable fastening.
What size spanner is needed for an M12 bolt?
To tighten or loosen an M12 bolt, you'll typically need a 17mm spanner or wrench. This size is standardized to fit the hexagonal head of the bolt, allowing for efficient and effective torque application. When choosing a spanner, ensure it's of good quality and the correct size to avoid slipping and potential damage to the bolt head or the spanner itself.
What are M12 stainless steel bolts used for?
M12 bolts are commonly used across industrial, commercial and construction sectors for various applications including:
- Mounting motors, pumps and actuators on industrial machines and equipment. M12 bolts provide a secure fastening.
- Joining sheet metal fabrications and enclosures for control panels and electrical boxes. Durable stainless steel resists corrosion.
- Attaching conveyor system rollers, skirting rubbers and belt alignment guides. M12 bolts are an ideal size for medium sized machinery.
- Fixing roof sheeting and cladding on agricultural and storage buildings. M12 stainless steel bolts will withstand weathering.
- Securing pipe clips, brackets and hangers in plumbing, HVAC and fire protection systems.
