M3 screw kit for precision builds

This 1002-piece AvrestYPT assortment supplies M3 button-head cap screws in eight lengths from 4 mm to 25 mm, plus matching nuts, flat washers and a hex wrench. The stainless-steel hardware resists corrosion in humid conditions. It suits 3D-printer upgrades, electronics enclosures, furniture assembly and light automotive work.

Verify thread and clearance before ordering

All fasteners use a 3 mm metric thread, so confirm that tapped holes, clearance holes and nut seats in your project are cut for M3. The shortest screws are 4 mm long and the longest 25 mm; ensure the grip length matches your material stack-up. No other thread pitches or diameters are included in the kit.

Compartmented case keeps sizes separate

The plastic box has labelled compartments for each screw length, nut and washer, preventing parts from mixing during transport or bench work. Stainless steel construction means the fasteners withstand repeated removal without rusting. The included hex driver fits every screw head, so no extra tools are needed for day-to-day adjustments.

Questions about this item

Does the 1002-piece kit include the hex wrench or must I buy one separately?

The kit contains M3 button-head screws in eight lengths from 4 mm to 25 mm, matching nuts, flat washers and one hex wrench inside the labelled plastic case.

Which screw lengths are useful for thin 3D-printer brackets versus thicker bed-frame joints?

Use the 4 mm and 6 mm screws for thin printed parts, the 10 mm to 16 mm range for standard brackets, and the 18 mm to 25 mm screws when fastening through thicker bed-frame or furniture material.

Will the stainless-steel M3 button-head screws hold up in a humid garage workshop?

Yes, the screws are stainless steel with strong corrosion, rust and oxidation resistance, so they remain reliable in damp environments.
