12 Point Flange Bolts

 Bolt Products’ line of  12 POINT FLANGE BOLTS are made to the dimensional requirements of the Industrial Fastener Institutes (IFI) standard IFI-115 (equivalent to SAE standard J58).

• Twelve Point Flange Screws are an alternative head design for hex socket cap screws. The flange diameter and head height are designed to fit applications and counterbored holes designed for standard hex socket cap screws.
• Twelve point flange screws are manufactured with the same thread length as socket head cap screws (2 times the diameter +1/2” minimum guaranteed threads).
• The twelve point head design is tightened with standard twelve point socket wrenches.
• The 12 point design permits greater torque to be applied to the bolt and eliminates the rounding of the hext socket that occurs with standard hex sockets.

12 Point Flange Bolt Material and Physical Properties are per ASTM A574: 

 Ma• •      • Material: Alloy Steel

   • Tensile Strength: 170,000 psi min

   • Proof Load Strength: 140,000 psi min

   • Rockwell Hardness: Rc 37/45 

The flange diameter and head thickness of the 12 Point Flange Bolt are equivalent to the head dimensions of a socket head cap screw. This permits the Twelve Point Flange Bolt to be a replacement for any application currently using a socket head cap screw. The twelve point design permits this style bolt to be tightened down with a twelve point socket wrench, which permits higher torque to be applied as compared to a standard internal hex drive socket head cap screw.

The higher strength and larger bearing area under the head of this design provides additional benefits for assemblies over standard hex head cap screws.
