Product Data Sheet –S-BT screw-in stainless steel and carbon steel threaded studs”, “Hilti Product Data Sheet –X-
FCM Grating Fastening System”, “Hilti Product Data Sheet –X-FCM NG Grating Fastening System”, “Hilti Product
Data Sheet –S-BT-ER / -EF”) for the recommended maximum loading in tension, shear, moment and torque, in
association with the recommended loads specified therein.
2. Refer to the Data Sheets for the application requirements to the followings:
a) Base material thickness and type of bore hole;
b) Thickness of fastened material;
c) Edge distance >= 6 mm [0.24”]; Spacing >= 18 mm [0.71”];
d) Corrosion information.
3. Service Temperature: -40 to +100 degree (Celsius)
Service Restriction:
Unit Certification is not required for this product. If the manufacturer or purchaser request an ABS Certificate for
compliance with a specification or standard, the specification or standard, including inspection standards and
tolerances, must be clearly defined.
1) The base material is limited to steel grade with the following properties:
a) For Steel as base material, Maximum ultimate tensile strength of steel fu = 630 MPa [91 ksi] & Minimum
ultimate tensile strength of steel fu >= 340 MPa [49 ksi];
b) For Aluminum as base material, Minimum ultimate tensile strength of aluminum fu >= 270 MPa [39 ksi];
c) Minimum thickness of base material tII: refer to the Data Sheet;
d) Maximum thickness of base material tII: no limits.
2) In general, type approved S-BT fasteners are NOT to be used for the following:
a) Shell plating (i.e. bottom plating, side plating, main deck plating);
b) Tank Boundaries
c) Weathertight boundaries where through penetration of the base materials is required;
d) Fire rated boundaries other than A0;
e) Structural members which require fatigue design;
f) Members with significant thermal stresses;
g) Highly stressed structural members
3) On Watertight bulkheads or decks (decks other than main deck or strength deck), the installation shall be to a
doubler plate, with no through penetration, welded onto the bulkhead/deck plating.
4) Hilti fasteners often may be used for the listed applications by following the Manufacturer's recommendations and
guidance. The attending Surveyor and Owner are to be consulted and agree with the use of the fasteners;
5) Hilti fasteners may also be used for additional applications other than those listed above. Some applications may
require an engineering review in advance.
6) Structural members that are sensitive to stress patterns or variations and in areas where notch toughness is of
paramount importance, the curve class S-BT (as per specification binder) applies for fatigue design for base materials
of thickness >= 4mm and yield strength ranging from 235 MPa to 355 MPa at an edge distance >= 15 mm.

Comments:
The Manufacturer has provided a declaration about the control of, or the lack of Asbestos in this product. ABS
approvals are general based on the product test reports furnished by recognized institutions and laboratories which
may reflect specific local conditions. If any application is in a jurisdiction where the fasteners are subject to the
