L-Bolts – Precision Anchor Bolts for Foundation & Structural Fastening
Product Description
L-Bolts, also known as L-Type Anchor Bolts, are bent fasteners with a 90° hook at one end, designed to be embedded in concrete and provide robust anchoring for structural loads. The “L” shape prevents pullout and offers enhanced hold for structural columns, base plates, industrial machinery, and steel frameworks.
At SM Fasteners, our L-Bolts are manufactured using high-strength mild steel, stainless steel (304/316), and high tensile steel. They are available in metric and imperial sizes, custom thread lengths, and finishes like hot-dip galvanizing, zinc plating, or plain black.
Applications
L-Bolts are widely used in concrete foundations where firm anchoring of steel structures or machinery is needed.
Typical Use Cases:
Foundation bolts for steel columns
Windmill and transmission tower bases
Securing heavy industrial machinery
Light poles and tower masts
Pre-engineered buildings (PEBs)
Highway sign supports
Pipe support anchorage in chemical plants
