they are corrosion resistant. the have good strength/structural integrity. they are reasonably inexpensive.

What fasteners to use with redwood?

Hot-dipped galvanized, aluminum and stainless steel fasteners are all corrosion-resistant and can be used to fasten Redwood or Cedar. Other types of nails and screws are not recommended.

Why is stainless steel used for fasteners?





Resistance to corrosion – stainless steel does not rust or tarnish giving you a better look and lasts longer. Strength – stainless steel is strong and it will hold up in harsh corrosive environments and it will also hold up in place with very high or low temperatures.

Are stainless steel screws rust proof?

When it comes to rust-resistant fasteners, stainless steel screws are the absolute best option. Stainless steel screws contain certain properties that allow them to withstand harsh outdoor elements to greater effect. As a result of their rust-resistant design, stainless steel fasteners see use in many outdoor projects.

Why are stainless screws good?

Stainless Steel Fasteners are, most importantly, corrosion resistant. They have an excellent life cycle, are environmentally friendly and are 100% Recyclable. They are also resistant to high heat as well as extremely cold temperatures making stainless steel fasteners the material of choice for almost any application!

Can I use stainless steel screws outside?

Stainless steel decking screws are another great option when it comes to outdoors screws and nails, as well as stainless steel screws. Both have properties that make them weather resistant, and are especially hardy against rain.

What are the best screws for decking?





A good all-around choice is #10 decking screws—generally in 2 1/2- to 3 1/2-inch lengths. Decking screws are sharp, tapered, self-sinking, and coated for corrosion resistance. With a cordless drill/driver, you can drive them about as fast as nails.

Which has better shear strength stainless or steel?

For both UTS and 2% yield strength, 440C stainless shines over the other steel and aluminum alloys in this comparison. 4130 alloy steel comes in a close second. Aluminums fall at the bottom in terms of UTS, but 304 stainless steel has the lowest 2% yield strength at 42.1 ksi.

Are stainless screws stronger than steel?

In fact, due to their low carbon content, many stainless steel alloys cannot be hardened through heat treatment. Therefore, when compared to regular steel, the stainless alloys used in bolts are slightly stronger than an un-hardened (grade 2) steel but significantly weaker than hardened steel fasteners.

Are stainless bolts stronger than Grade 8?

Stainless Steel Grades & Strength



Bolt strength is rated in PSI (pounds per square inch). A stainless steel bolt has the same PSI rating as a grade 5 bolt (125,000 PSI). A grade 8 bolt has a stronger rating with a PSI of 150,000.

What is stronger zinc or stainless steel?

Choosing Between Zinc Alloys and Stainless Steel

Though some Zinc alloys can be very strong, overall stainless steel is stronger. However, zinc is a heavy element, and when alloyed with other metals it provides better corrosion resistance, stability, dimensional strength and impact strength.

What is the strongest stainless steel screw?



BUMAX® Ultra has proven itself as the world’s strongest bolt – in various highly-demanding critical fastener applications around the world where standard fasteners are simply inadequate.

What is the best stainless steel screw?

Most builder needs for screws and fasteners fit into the 18-8 (Types 300-304 grade stainless steel), Type 305 stainless screws are recommended for decks, Type 316 stainless steel for builds around chlorine, saltwater and other corrosive atmospheres, while Type 410 stainless self-drilling screws are used when extra …

Is 304 or 316 stainless steel better?

Most stainless steel ordered around the world is Grade 304. It offers the standard corrosion resistance, formability, strength, and easy maintenance for which stainless is known. While 316 comes in second in terms of quantities sold, it offers vastly superior corrosion resistance to chlorides and acids.

Is 410 or 304 stainless steel better?

18-8 stainless steel, also sometimes called 304 stainless, is the most common type used for fasteners such as machine screws and nuts. It contains 18% chromium and 8% nickel and features strong corrosion resistance, but is softer, and thus weaker, than some other grades such as 410 stainless.
