#12 x 5ft Sheet Metal Screws 100PCS Hex Washer Head - Durable 410 SS

In this review of the #12 x 5' Sheet Metal Screws 100PCS by SG TZH, the bottom line is simple: these screws suit anyone needing a heavy-duty, long 5' self-tapping fastener for wood, metal or plastic where corrosion resistance and strength matter. The reviewer found the set most useful for door hardware, floor fixing and workshop repairs because the 410 Stainless Steel construction and sizeable hex washer head deliver solid holding power and easier installation for larger projects.

Key Features

• Material: 410 Stainless Steel offers improved corrosion resistance over ordinary steel, extending service life for many indoor and semi-exposed projects.
• Head design: The Hex Washer Head reduces slippage and spreads load, making it easier to start and sink the screw without stripping.
• Size and strength: The #12 diameter and 5' length provide substantial bite and shear strength for fastening thicker materials or stepping through multiple layers.
• Self-tapping threads: Precision threads cut and pass through plastics, wood and thin metals, simplifying installation without separate tapping.
• Value pack: The 100PCS packaging supplies enough fasteners for larger jobs or repeated small repairs, reducing trips to the hardware store.

Who It's For

These screws are aimed at homeowners, contractors and hobbyists who need robust, long self-tapping fasteners for tasks like installing door handles, securing floor fixtures or making small mechanical repairs. The set works well in a garage or shop where a supply of large sheet metal screws is regularly used.

Those who need fully non-magnetic stainless alloys or guaranteed marine-grade corrosion resistance should look elsewhere, as these are 410 Stainless and can show magnetic attraction; customers requiring fine-thread machine screws or very small sizes will also want a different product.

Pros & Cons

Pros

• Durable 410 Stainless Steel construction gives better rust resistance than ordinary steel for longer service life.
• Hex Washer Head design helps prevent driver slippage and spreads clamping force for more secure fastenings.
• Generous 5' length and #12 diameter provide strong holding power through thick materials or layered assemblies.
• Bulk 100PCS pack is economical for repeated jobs and workshop use.

Cons

• 410 Stainless is magnetic and not the highest corrosion grade, so very harsh or marine environments may show rust over time.
• Some users report mixed experiences with rust resistance in long-term outdoor exposure.

Our Verdict

The #12 x 5' Sheet Metal Screws by SG TZH are a practical, value-minded choice for workshop and home repairs where strong, long fasteners are needed. Their hex washer head and 410 Stainless construction make them reliable for interior and some exterior applications, but buyers needing the highest corrosion resistance or non-magnetic stainless should consider a different alloy.
