Yes, A2-304 stainless steel is highly resistant to corrosion and suitable for most outdoor, non-marine environments.
These screws feature a Pozi countersunk head, designed to sit flush with the surface.
While they are self-tapping, pre-drilling a pilot hole is recommended for hardwoods to prevent splitting.
A2-304 stainless steel is generally non-magnetic, though some minor magnetism may occur due to the cold-working process during manufacturing.
6G refers to the gauge or diameter of the screw, which is approximately 3.5mm.
Each box contains 1000 individual screws.
Ensure you are using the correct size Pozi bit and decrease your drill's torque setting to prevent over-driving.
Create a pilot hole using a slightly smaller drill bit to guide the screw and reduce friction.
Ensure no carbon steel particles or abrasive dust from nearby metal cutting are on the surface, as these can cause 'tea staining' on stainless steel.
To ensure the best performance, always use a high-quality Pozi drive bit that matches the screw head size exactly. While the screws are self-tapping in many metals, it is recommended to drill a small pilot hole when working with extremely hard woods to prevent the screw from snapping or the wood from splitting. Keep the screws in their original storage box in a dry area to prevent cross-contamination with carbon steel tools, which can cause surface oxidation on stainless steel fasteners over time.
