#10 Flat head phillips drive self tapping screws made of stainless steel. Sometimes called sheet metal screws or self tappers, these fasteners are common for home repairs as well as installing hardware on your boat. Flat Head is the most common screw head type, and is used for general fastening when the screw head will be flush with the surface, or when it will be countersunk and the hole will be plugged. Phillips drive allows greater torque to be applied when fastening.

Self Tapping screws are designed for use in sheet metal but are great for mounting hardware onto laminates, wood, and for many other applications. Self tapping or sheet metal screws have a deep thread that goes all the way up the shank to the head. All of our Self Tappers have an A point.

Can you tell me what the specification of the stainless steel is in this item? What is the difference between this item and the #10 Self Tappers FP 316 S/S? The application is for fixing heavy shower doors to walls. Thanks.
Stainless Steel: This was copied from Jamestown distributors.When to Use It, and What Do the Numbers Mean? Stainless Steel was developed about 90 years ago to solve the rusting problems of standard grades of steel. It is best used where the eventual corrosion of plated products would create a real problem Â’Â¢?? salt-water boats or docks (above water), and redwood siding quickly come to mind.Only a few of the many engineered grades of Stainless Steel are suitable for fasteners Â’Â¢?? those that can be Â’Â¢??cold headedÂ’Â¢?? easily, are corrosion resistant, and have adequate torsional and shear strengths. Of these, the 300 series of stainless steels is most popular. These alloys contain about 18% chromium and 8% nickel for good corrosion resistance, but make them non-magnetic and non-heat-treatable. Differences between 304 and 305 series stainless steel are slight, but 316 stainless adds molybdenum, which increases corrosion resistance, strength, and cost. Stainless Steel must be Â’Â¢??PassivatedÂ’Â¢?? for use below the water in marine applications. Non-Passivated screws may corrode quickly if they donÂ’Â¢??t maintain contact with the flowing oxygenated water which is required in order to form the chromium oxide film which protects them against galvanic corrosion and eventual failure.When a bit of corrosion resistance can be sacrificed for strength and reduced cost, 410 stainless steel is used. It contains about 12% chromium, no nickel, and sufficient carbon to allow heat treatment, making it mildly magnetic. Because it can be heat-treated, it is used extensively for self-drilling fasteners. It has a slightly Â’Â¢??coatedÂ’Â¢?? surface finish appearance.

Thank you for the information David. 316SS it is!
Thank you for taking the time to answer Burt.
I assume you are comparing 304SS to 316SS. In a wet enviroment, I would use 316SS. No matter what they say about marine or any other wet situations, use of 304SS will bleed rust over time if damp. Do it right, spend a litle more, use 316SS if posible.
Definitely would buy these again!!

Product better than expected, service ex
Unable to source product at local large national building products store and was happy to find Jamestown on the web. Great selection, very reasonable pricing and quality was excellent. Promptly shipped and received in short time.
