Sanko Techno Sanvic Anchor NSB Type Steel Metric Screw NSB-1250 1 Piece

Catalog number: NSB-1250 Features: ● Torque management during installation. ● Maintains strength even in areas subject to repeated loads. ● Parallel expansion and fastening allows installation with small variations in strength (standard deviation). ● Can be installed from above the object being attached, eliminating misalignment of the installation position. ● Ideal for areas requiring shear strength as well as tensile strength. Uses: ●For concrete●Installation of medical equipment, communication rack installation, silt installation, plant facility construction, equipment installation, etc. Specifications: ●Screw size: M12●Maximum thickness of object to be attached (mm): 50●Drill diameter (mm): 18.0●Maximum tensile load (kN): 45.3●Effective embedment depth (mm): 74●Outer diameter (mm): 17.6●Drilling depth (mm): 145●Total length under neck (mm): 135●Neck length (mm): 135●Boxed Material/Finish: ●Steel●Trivalent chromate treatment●Surface treatment: Trivalent chromate treatment Caution: ●The maximum tensile load is the value when the concrete strength Fc=21N/[[MM2]]. ●Be sure to remove the chips from the pilot hole. ●The drilling depth varies depending on the thickness of the object to be attached. ●Standard torque (N・m): 80 should be used.
