Question 1

Will they work for plastic parts?

Accepted Answer

Some self tapping screws for plastic or plastic screws are designed with threads that grip softer materials, but metal-focused screws may crack plastic if the size or drive torque is wrong. For screws for plastic, test fit and avoid overtightening.

Question 2

Are these stainless steel or coated steel?

Accepted Answer

Check materials before choosing. Buyers searching for stainless steel self-tapping or sheet metal screws seek better corrosion resistance than plain steel, but exact performance depends on grade and environment.

Question 3

Are these strong enough for structural wood work?

Accepted Answer

Use structural wood screws only when specifically rated for structural loads. General self-tapping assortments shouldn't substitute lag screws or bolts unless the manufacturer provides load data.

Question 4

Are black screws different from silver screws?

Accepted Answer

Black screws indicate color, not strength. For metal or sheet metal variants, specify if the finish is oxide, coating, or paint, and clarify its effect on corrosion resistance.

Question 5

Is this a full screws assortment kit?

Accepted Answer

Assortment kits must list piece counts, sizes, and compartmentalization. Buyers comparing screw or wood screw assortment kits need exact contents before purchase.

Question 6

Can these be used for repair around the house?

Accepted Answer

They can help with many light repairs when the material and size match. For general screws, screw, and small screws searches, buyers need clear size labels more than broad claims.

Question 7

Can these replace deck fasteners?

Accepted Answer

Only position a product as a deck fastener if it is specifically rated for decking. Deck screws are chosen for corrosion resistance and outdoor holding power, so metal screw kits should not be presented as such by default.

Question 8

Are these good for brackets and hinges?

Accepted Answer

For brackets, hinges, and light hardware, mounting screws or cabinet screws may work if the head sits correctly and the screw length does not protrude. Show head dimensions so buyers can judge fit.

Question 9

Will these rust?

Accepted Answer

Rust resistance depends on material, coating, and environment. Stainless steel screws or stainless steel self tapping screws generally target corrosion resistance, while coated black screws may vary by coating type.

Question 10

Can these be used with washers?

Accepted Answer

If washers are included, state the washer material, size, and whether they are for load distribution or sealing. Metal roofing screws and roofing screws often use washers, but do not imply a waterproof seal unless the washer design supports it.
