In addition, specifying a Safe Working Load would involve dividing the 3-Sigma Yield Load by a Factor of Safety. Only one of the tested anchors are strong enough to provide a reasonable Safe Working Load: the S1 Glue-In Stud.

Upat Ampoule - UKA 3
Hilti HIT-HY 150 installed with Hilti Injection gun
Epidermix 372
n/a = not enough tests to compute

S = Stud
M = Mechanical expansion
