Hex Bolt / Screw
Hex Bolt / Screw
Hex bolts, also known as hex head bolts or cap screws, are essential fasteners characterized by their six-sided (hexagonal) heads, facilitating easy tightening with wrenches or sockets. They are widely used in construction, machinery, and automotive applications for securing materials like metal, wood, and plastic.
Key Features:
-
Head Design: Six-sided (hexagonal) head for easy gripping and tightening.
-
Thread Types: Available in coarse (UNC) and fine (UNF) threads.
-
Materials: Manufactured from steel, stainless steel, brass, and nylon.
-
Sizes: Range from M10 to M56 (metric) and 0.4" to 2.2" (inch), with lengths from 20 mm to 300 mm.
-
Finishes: Options include zinc plating, hot-dip galvanizing, and black oxide for corrosion resistance.
Application:
-
Standard Hex Bolts: Used in construction, machinery, general assemblies; strong, versatile
-
Heavy Hex Bolts: Ideal for structural steel, bridges, heavy equipment—higher load-bearing
-
Self-Drilling/Tapping Hex Screws: Used in roofing, sheet-metal, HVAC; eliminate need for pre-drilling
-
Hex Cap Screws: Precision fasteners; used in OEM, electronics, machinery with tight fit demands
