Hex Head Cap Screw: 1/4-28 x 3-1/2", Grade 8 Steel, Zinc Yellow Dichromate Finish MPN:1428312FT8ZYDOM

The Hex Head Cap Screw with a size of 1/4-28 and a length of 3-1/2 inches, made from Grade 8 Steel and finished with Zinc Yellow Dichromate for added corrosion resistance, offers excellent tensile strength. This product is perfect for applications in the construction, mechanical, or general engineering industries that demand superior performance. It can also be utilized in marine and outdoor environments where the elements pose a challenge to regular steel fasteners because of its durability against rust or galvanic corrosion. Due to its grade 8 material, it provides significant strength-to-weight ratio when tightening and provides consistent clamping force making it an excellent choice for permanent installations requiring high resistance to vibrations or dynamic loading. With its uniform helical threads and chamfered end, this cap screw ensures smooth thread engagement with the tapped hole while reducing risk of damage from accidental over-tightening during installation thus minimizing risk of stripping or cross-threading.
