Nuts & Bolts on Chula Vista's Main Street corridor stocks standard and metric fasteners in every grade, thread pitch, and finish for construction, industrial, and automotive applications. The inventory spans hex bolts, carriage bolts, machine screws, lock nuts, flat washers, and split-lock washers in steel, stainless, and brass — the same hardware categories pulled by plumbing contractors at Solid Plumbing & Drains Inc for pipe-hanger and bracket assemblies. Metric-thread fasteners cover DIN and ISO specifications from M3 through M20, filling a gap that big-box hardware stores typically leave for specialty distributors. The wholesale side ships bulk orders to fabrication shops, fleet-maintenance yards, and independent mechanics including the technicians at Bonita Point Auto Care 76 who source hard-to-find OEM-spec engine and suspension bolts. Specialty stock includes Grade 8 and Grade 10.9 high-tensile fasteners, Class 12.9 socket-head cap screws, and A2-70 stainless steel hardware rated for marine and corrosion-prone environments.
