The shear strength of heat-treated steel and the dielectric insulation,
corrosion resistance and vibration resistance of nylon.
These reinforced screws will provide up to 4 times the strength of standard nylon fasteners.
Due to the corrosion resistant nature of the nylon, the Metal Core Screws can, in certain applications,
replace expensive Stainless Steel, Brass and Monel fasteners at a substantial cost savings.
Metal-Core Screws are recommended in applications requiring electrical, thermal and vibration
insulation in shear or double shear connections. The reinforcing core incorporates a recessed
metal head that permits tightening with high speed, high torque automatic drives.
