Description

A2 (1.4301 [304] grade) austenitic stainless steel self drilling fastener with 6.0 mm diameter threads into the purlin/ rail . The fasteners are designed for securing halters for aluminium standing seam systems.

Head drive:

The uniquely designed fastener is driven via a square peg above a 7 mm hexagon head. The tapered section below the head engages in the 6.1 mm punched hole of the halter, which is clamped to the purlin/rail. When the correct torque is reached the peg breaks off to ensure the fastener are not overdriven.

If a halter needs re-positioning the socket is reversed and the SDK fastener may be removed via the 7 mm hex drive.

Up to 40 years (period to be confirmed and agreed specific to the project).

Approvals:

Suitable to be used with all major aluminium standing seem manufacturers, subject to halter specification.
