The chain is fine...but I ordered the wrong size. Nine links of the chain I ordered equals six of the size I wanted. My error...
How can I straighten out the springs? I can't use them coil uo as is.

Small fasteners, big reliability — that’s what you get with these Phillips pan-head self-tapping screws from GooBetter Fastener. The bright nickel plating not only resists corrosion in humid or indoor environments but also keeps the heads looking clean on faceplates, electronics enclosures, and visible hardware. Because they’re self-tapping, you drive straight into sheet metal, plastic, or wood without pre‑drilling or tapping — a real time‑saver on the bench and in the field. The pan head sits flush with a neat, rounded profile that won’t catch on wires or clothing. Available across eight diameter sizes from M1 to M3, this assortment puts the right screw within reach for precision electronics, RC models, appliance panels, light‑duty automotive trim, and general shop repairs.

Yes, nickel plating provides superior corrosion resistance in humid, indoor, and light‑duty outdoor environments compared to standard zinc. It also keeps a bright, silver‑white appearance that looks clean on visible fasteners.
They perform well in softwoods, hardwoods, and sheet metal alike. For very dense hardwood, a small pilot hole (about 80% of the screw diameter) makes driving easier and protects the thread.
For thin sheet metal up to about 1.2 mm, you can usually drive them straight through. Thicker or harder materials benefit from a pilot hole to reduce drive torque and give the cleanest thread engagement.
The smallest screws (M1–M1.7) take a #0 bit, M2–M2.6 use #1, and M3 works with a #2 bit. A bit in good condition prevents cam‑out and keeps the head recess intact.
Absolutely. Every screw ships in GooBetter Fastener-branded packaging and goes through a quality check for thread sharpness, plating uniformity, and dimensional accuracy before dispatch.
