FAQ
Q1. How many pieces are in this M2 socket head cap screw kit?
820 counted pieces: 420 screws across seven lengths, 200 M2 nuts and 200 M2 flat washers. One hex key is included but not counted in the 820.
Q2. Which lengths are included?
M2 × 4, 6, 8, 10, 12, 16 and 20 mm, 60 pcs of each length.
Q3. What does black zinc plating give?
A clean black appearance plus basic surface protection. The image describes it as a clean black appearance with basic surface protection, so it suits indoor and general assembly rather than prolonged salt-water exposure.
Q4. Are the black zinc plated M2 screws strong enough for structural use?
The images give no property class or tensile strength, and the product itself recommends small-scale, light-duty assembly. For load-bearing joints, confirm the required grade and torque with your engineering specification.
Q5. Why are M2 screws for 3D printing included in this kit?
Because printer accessories, enclosures and custom builds use repeated M2 lengths. Having 4–20 mm in one case avoids buying single lengths during a build or repair.
Q6. Do the threads match the included nuts?
Yes. The screws, nuts and washers are all M2, and the image describes clean, uniform threads for smooth engagement with matching M2 nuts or threaded holes.
Q7. Is the hex key counted in the 820 pieces?
No. The image states 1 × hex key included and not counted in the 820 pieces.
Q8. Is this kit in stock?
Yes, ready stock is available for the standard configuration. Quantity and dispatch time are confirmed at order stage.
Q9. Can I change the length mix or the nut and washer quantity?
Yes. In-box contents are customizable, including the length list, quantity per length and the nut and washer ratio.
Q10. Can the box, label and logo be customized?
Yes. OEM packaging covers custom labels, inserts, barcodes, box options and private label programs.
Q11. What is the case size and carton data?
125 × 64 × 20 mm per case, 195 g net weight, 96 boxes per 28 × 25 × 25 cm carton. Gross weight and pallet data are not stated in the images.
Q12. Can I order samples before a bulk order?
Yes. The image lists samples among the items to request, together with bulk pricing.
Q13. Are certifications available?
No certification mark is visible on the images. If your market requires test reports or declarations, raise the requirement at quotation stage.
