M30 X 140 Hexagon Head Bolt 1 Pack ISO 4014 A4-80 A4 Stainless Steel
- RRP
- £28.01
This M30 x 140mm part threaded hex bolt is manufactured to ISO 4014 in A4 stainless steel (316 grade). ISO 4014 specifies a hex head bolt with a plain shank beneath the head and thread over the lower portion only, making it suited to joints that carry shear across the joint line. Property class A4-80 indicates a minimum tensile strength of 800 MPa - stronger than standard A4-50 and suited to structural fixings where higher clamping force is needed. The unthreaded shank sits in the bearing hole rather than the thread, locating the joint accurately and presenting a solid cross-section to shear loads instead of the reduced root diameter of a thread.
Typical applications
- Structural steel and heavy timber connections
- Pivot points, brackets, and load-bearing joints
- Machinery frames and equipment mounting
- Applications where the joint carries shear rather than tension
Available singly and in packs of up to 5, with free next working day delivery on UK orders over £50 and 30-day returns.
