Reverse Counterbore: 3/4" Dia, 5/16" Pilot Hole, 4 Flutes, High Speed Steel MPN:190-9K
The Machine screw 1/4-20 x 2-3/4 Flat Head Phillips is primarily used for fixing or fastening material together by engaging with the pre-drilled hole and rotating to create pressure against the external part. This screw offers high precision, excellent torque resistance, and durability as it is made of quality metal, typically steel, that prevents rusting in different atmospheric conditions. Its application ranges from automotive repairs to electronics and aerospace engineering, with the advantage of varying sizes, lengths, and heads to match specific hardware requirements. Additionally, flat head screws like this provide low-profile mounting solutions that preserve clearance for other elements in tight spaces. They are user-friendly and come with a standard Phillips drive tip that assists users in driving or loosening them efficiently without the need for any special tools beyond basic hardware.
