Hex bolts
Hex bolts are used widely in aircraft construction, in situations where shear loads and tension are prevalent, and where a light drive fit is possible. With a range of standard hex bolts available in stainless steel or alloy steel, the products in our portfolio can be adjusted to meet clients’ needs while adhering to industry requirements.

We at CalScrew possess full industry certifications and accreditations. We are associated with the IFI – the Industrial Fasteners Institute and as such are at the forefront of the industry, setting best practice and leading innovation. Additional accreditations and certifications include AS9100 REV D and ISO9001.
