Common Concerns Answered
Will this screw corrode in saltwater?
Constructed from 18-8 stainless steel, this hex cap screw offers excellent resistance to corrosion typically encountered in marine environments. For extreme conditions, 316 stainless steel is an alternative, but 18-8 is generally sufficient for most applications.
What type of torque can I apply?
The hex head design allows for secure torque application with standard wrenches. While specific torque values depend on the mating material and nut, this screw is rated for a minimum tensile strength of approximately 70,000 psi.
Is this screw suitable for underwater applications?
Yes, its 18-8 stainless steel construction makes it highly suitable for underwater use, providing reliable fastening that resists degradation from constant submersion in saltwater.
Frequently Asked Questions
What is the thread pitch for this screw?
The thread pitch is 16 threads per inch (TPI), which is designated as UNC (Unified National Coarse) for a 3/8-inch diameter screw.
What is the recommended tool for installation?
A standard socket or wrench designed for 3/8-inch hex heads is recommended for proper installation and to achieve optimal torque.
Can I use this screw with different metal types?
This screw is compatible with most marine-grade metals. However, be mindful of galvanic corrosion when pairing with dissimilar metals; use washers or consider 316 stainless steel for critical applications involving highly reactive metals.
What is the tensile strength of this fastener?
The minimum tensile strength for this 3/8-16 stainless steel screw is approximately 70,000 psi.
How is the length measured on this screw?
The 2-inch length is measured from the underside of the hex head to the extreme end of the screw shaft.
