Stainless Steel Fasteners & Bolts: A2-70 & A4 Solar Hardware Guide
Marine-grade A2-70 and A4 stainless steel socket screws, T-bolts, spring channel nuts, and serrated flange nuts engineered for 25-year longevity.
4 Key Engineering Selection Criteria for Stainless Steel Fasteners & Bolts
A2-70 (AISI 304) vs A4 (AISI 316)
A2-70 is standard; marine A4 is specified for sites within 5 km of coastlines or chemical atmospheres.
Hammerhead & T-Bolt Lock-In
Head turns 90° in rail channels, locking against internal lips upon tightening.
Spring Channel Nuts
Integrated spring holds nut firmly in rail slot during overhead vertical alignment.
Serrated Hex Flange Nuts
Base teeth eliminate the need for separate lock washers and resist vibration loosening.
