) where t
fix max
is provided in Table 3B and t
fix
is the thickness of the part(s)
being fastened.

Sleeve recess after setting of the anchor:
a) Pre-setting anchor HDA-P(R): distance from surface of the concrete member to top edge of the anchor sleeve (see Figure 1)
b) Through-fastening anchor HDA-T(R): distance from top edge of the fixture to top edge of the anchor sleeve (see Figure 2)
