- Electronics small parts
- Rust proof
The GLARKS 510-piece kit is the go-to for small, rust-prone repairs: 304 stainless resists rust for wet or outdoor use, and it includes matched M2-M5 machine screws, nuts, and flat and split-lock washers in a labeled box. But the small sizes are never structural, the pan-head Phillips strips if over-torqued, and it's metric-only with no hex bolts.
Pros
- 304 stainless resists rust, so it works outdoors and on anything that gets wet — a real upgrade over zinc kits
- Includes both flat and split-lock washers plus matching nuts for genuine small-fastener repairs
- Labeled compartment box makes finding an M3 vs M4 fast
Cons
- Small sizes only (M2–M5) — nothing here is structural or load-bearing
- Pan-head Phillips strips easily if you over-torque soft stainless
- Metric machine screws, not SAE, and no larger hex bolts
