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.

A low‑profile head that holds tight without sticking out — that’s the advantage of these Phillips modified truss self-tapping screws. Designed for sheet metal, wood, plastics, and composite panels, the wide bearing surface spreads clamp force over a larger area, preventing pull‑through in thin or soft materials while sitting nearly flush. The bright nickel plating delivers dependable corrosion resistance for indoor and light outdoor use, and it adds a clean, professional look to visible fasteners. From electronics chassis and HVAC ductwork to automotive trim and DIY furniture, GooBetter Fastener packs the full M1.2 to M4 size range so you’re equipped for precision assembly work and general shop repairs alike.

A modified truss head has a wider bearing surface than a pan head but a lower profile than a standard truss. It spreads the clamping load to prevent the head from pulling through thin or soft materials, and it sits flush with the surface — great for sheet metal, plastic panels, and anywhere you need a clean, low‑profile finish.
Nickel plating offers better corrosion resistance than standard zinc in humid or mildly acidic conditions, and it keeps a bright, silver‑white appearance. Unlike black oxide, nickel doesn’t rely on an oil film for protection. For indoor electronics, furniture, and light outdoor gear, nickel is a solid upgrade.
Yes. They cut into softwoods and hardwoods without issue. For very dense or brittle hardwoods, we suggest drilling a pilot hole about 80% of the screw diameter to reduce drive torque and lower the risk of snapping.
A standard Phillips bit in the correct size works perfectly — #0 for the smallest screws (M1.2–M1.7), #1 for M2–M2.6, and #2 for M3–M4. Using a fresh, unworn bit helps prevent cam‑out and protects the screw head.
Absolutely. Every pack ships in GooBetter Fastener-branded packaging and is inspected for thread form, hardness, and plating quality before dispatch.
