Staytite will be demonstrating the HARDLOCK Nut at the forthcoming SUBCON exhibition

Staytite will be demonstrating the HARDLOCK Nut at the forthcoming SUBCON exhibition providing a hands-on experience and discussion about the problem of loosening fasteners.  Our team will explain the benefits of using the HARDLOCK Nut, a proven fastener that resists loosening, currently in use across many applications and industries.

How it works:

The HARDLOCK solution utilises the wedge principle.  Firstly the lower convex fastening nut generates axial torque in the same way as a normal nut.  Importantly this nut has a small eccentricity at the upper convex.  Then, as the upper concave lock nut is tightened, the wedge effect generates stress perpendicular to the axis, which pushes the lower convex nut against the screw thread. When the upper concave nut is completely tightened, the HARDLOCK Nut produces a stable self-locking force with the result that it remains unaffected by external vibration or impact.

The HARDLOCK Nut has met the testing requirements of multiple vibration and impact tests including the NAS3350 and 3354 National Aerospace Standard.  Its proven reliability enables its users to benefit from a significant reduction in their maintenance costs.

Our team will be on-hand with samples on our Staytite stand.  Alternatively you can visit: www.hard-lock.co.uk or call Staytite 01494 462322.
