More About Part Number 277244

These 5/16-18 x 5" Thread Cutting Screws feature a Pan Head with a Six-Lobe Drive and are made from Steel. Thread cutting screws create mating threads by cutting into the material during installation, making them useful where a screw must form secure threads in preformed holes. Type F thread cutting screws are designed to cut machine-quality threads in sheet metal, castings, and similar materials. They feature a Black Phosphate Finish, which offers moderate corrosion protection and improved paint adhesion and is commonly used as a base coat in manufacturing applications. The Pan Head features a slightly rounded top with a flat bearing surface, offering a versatile profile commonly used in sheet metal and general fastening applications. The Six-Lobe Drive offers increased torque transfer, decreased stripping and extremely low cam-out.
