Kreg Stainless Screws are specially designed for maritime applications, excessive exposure to water, and other exceedingly corrosive environments, such as ACQ-treated lumber.

If you are looking for the best in rust prevention, this is your solution.

Stainless Steel: No discussion of corrosion resistance would be complete without mention of stainless steel screws. Although all products corode sooner or later, stainless steel provides excellent protection. Since the carbon content of stainless is quite low, oxidation (rusting) is also quite low. However, the steel cannot be treated adequately because of the low carbon content. As a result, the screws are soft and break easily when used in wood applications where high levels of torque strength are required. Pre-drilling all screw holes and using larger gauges of screws can compensate for this problem.

The Nickel used in manufacturing Stainless Steel make them non-magnetic and will not hold to a magnetic bit.

The Type 17 point is not a thread style but can enhance the performance qualities of most thread styles used in the woodworking industry. A slot or notch is cut out at the point of the screw that acts like an auger or drilling tip. The slot carves away the material, thus allowing it to self-drill into most types of wood. It can often eliminate the need for a pre-drilled hole to relieve splitting. The Type 17 point is excellent for hardwoods, softwoods, particleboard, and especially MDF.

Robertson® Square Drive has a more positive fit that reduces "cam out" and requires only 4 foot-pounds of pressure to keep the bit engaged. An early attempt to introduce these Square Recess Screws into the United States failed so they were confined to the Canadian Market until the 1970s. The Phillips Head was introduced in the 1930s and would cam out instead of being over-torqued by the new power drivers of the time.

FEATURES:

• 305 Stainless Steel
• A self-drilling auger point.
• Coarse Threads
• Robertson® Square Drive for non-slip bit engagement.

Use a clutch equipped drill to avoid the disaster of over tightening.
