ASMC Industrial - Step Bolt - (FT) Coarse Thread A307 Grade A, Hardware Steel Bolts for Pool Stairs, Deck Ladder, and Repair Projects, Low Carbon Steel, Zinc Plated - 1/4"-20 x 1 1/2", Pack of 100

ASMC Industrial's 1/4"-20 x 1 1/2" Step Bolt features a premium design with a large, low-profile round head and square shoulder preventing rotation during installation while creating smooth surfaces for deck construction, stairs, ladder steps, pool deck applications, and garage door hardware projects. Made from high-quality low-carbon steel meeting ASTM A307 Grade A specifications with durable zinc plating for excellent corrosion protection in outdoor environments, this bolt delivers superior tensile strength for structural applications while significantly extending service life compared to standard bolts and nuts. The exact 1/4" diameter and 1 1/2" length with full thread coverage ensure consistent performance, while the unique step bolt design provides 40% larger bearing surface than carriage bolts, offering superior pull-through resistance. The square shoulder prevents spinning during tightening, enabling faster single-sided installation compared to standard door bolts while maintaining secure connections, and can be used with washers for enhanced load distribution. ASMC Industrial fasteners are lot-controlled with full traceability and rigorous testing, ensuring consistent quality for professional standards. Packaged in 100-piece quantities perfect for contractors needing reliable small bolts and nuts, door screws, bolt and nut sets, garage door parts and hardware, and extension ladder parts for multiple construction applications requiring quality, reliable hardware solutions.
