X-CR M Stainless Steel Threaded Stud
Product Information:
The X-CR M is a stainless steel threaded stud designed for
fastening to concrete and steel. It features a threaded sleeve made
of A4 (AlSi 316) stainless steel and has a zinc coating on the
shank. The product dimensions for the X-CR M8-__-42 P8 (DX-Kwik)
model are as follows:
- Threaded sleeve: A4 (AlSi 316)
- M8 o 6.3
- o 4.5 o8
- Lg: 42
- L: Material specifications Shank
The X-CR M8-__-42 P8 (DX-Kwik) model is suitable for various
applications including base plates for pipe rings, installation
rails, facade brackets, and special purpose connections. It has
received approvals from DIBt (Germany).
Product Usage Instructions:
Before using the X-CR M, always review and follow the
instructions accompanying the product.
Fastener Selection:
Refer to the Fastener selection guide in the Direct Fastening
Manual (DFTM) for recommended resistance under tension load, shear
load, and bending moment.
Fastening to Concrete:
For fastening to concrete, follow the recommended fastener
positioning in the base material. The X-CR M8-__-42 P8 model
requires a minimum base material thickness of 100 mm. The
positioning of the fasteners can vary depending on the
application:
- Pairs
- Row along edge
- General (e.g. group of fasteners)
For reinforced and non-reinforced base material, different
distances (c and a) should be maintained. Reinforced base material
should have a minimum of 6 reinforcing steel continuous along all
edges and around all corners, with edge bars enclosed by
stirrups.
Application Limits:
There are no general restrictions for fastening to concrete.
Limitations are dependent on the specific application and user
requirements.
Corrosion Information:
Refer to the Handbook for corrosion information.
System Recommendation:
For soft/medium concrete, use the DX 6 F8 tool with a titanium
cartridge (2-6). For tough concrete, use the DX 5 F8, DX 460 F8, DX
36, or DX 2 tool with a titanium cartridge (4-8).
Cartridge Recommendation:
Use the 6.8/11 M cartridge for both soft/medium concrete and
tough concrete.
Installation Recommendation:
Pre-drill with the TE-C-5/23B or TE-C-5/23 drill bit. Tighten
the X-CR M threaded stud with a torque of 10 Nm.
Quality Assurance:
Refer to the Fastening inspection section for quality assurance
details.

· DX-Kwik method (pre-drilling) for fastening to concrete: fcc 20 N/mm2. · A sufficient redundancy has to be ensured, that the failure of a single fastening will
not lead to collapse of the entire system. · Observance of all pre-drilling requirements. · For more details in relation to base material properties, please refer to the chapter
Fastener selection guide in the Direct Fastening Manual (DFTM).
