self locking nuts
Aerotight Manufacturing Aerotight®
all-metal
. The nut is available in most thread forms, including Metric, UNC, UNF, BA, BSW and BSF. Customer specials - for example thin types - are available to order. Aerotight Manufacturing is part of the Apex Stainless Fasteners Organisation.
Aerotight Manufacturing offers the time-proven solution to vibration problems. The Aerotight nut has built a reputation for quality and reliability over many years, with a well-proven design that has become established throughout industry. It is the leading all-metal stainless steel self-locking nut and is also available in brass, aluminium or steel. There are no vulnerable inserts to be affected by heat or oil and it is re-useable, with the self-locking function remaining effective. In both its steel and stainless forms it can be used up to 300°C. The Aerotight nut will remain in position whether tightened down or not, providing the locking element is engaged, and does not have to achieve recommended torque to be effective. No additional parts are required for the Aerotight to function so no special tools are needed. All stainless steel bar used in the manufacture of the M5 to M20 range achieves an ultimate tensile strength of 700N/ mm2
Bülte Plastics
Secure, tight assemblies Bülte Plastics’ locking and sealing washers keep a tight grip on all standard screws, nuts, and bolts. They dampen vibrations and noise, increase the contact surface and protect fragile surfaces from damage.
Each locking and sealing washer has two lips which dig into the pitch of a nut or screw and any empty space in an assembly to provide a completely tight and secure seal.
For safety reasons and to ensure a tight seal, never re-use washers. They deform easily around part of the head of the screw and nut and do not flex back to their original shape.
Generally made of natural polyamide, Bülte Plastics’ washers can also be made of polyethylene, PVDF and more flexible materials on request. They are highly resistant to chemicals and have good ageing properties.
Bülte Plastics can custom-manufacture washers to your exact specifications; diameters and colours.
