Hex Bolts

Hex Bolts

Hex bolts are designed for high-torque applications where durability and strength are crucial. Their six-sided head makes it easy to get a tight grip with a wrench or socket, allowing for more torque with each turn. Hex bolts can also be used with tapped holes or nuts for added versatility when needed. 

Hex bolts (also called hex cap screws or hex cap bolts) are some of the most widely used fasteners in construction and repair. They are ideal for structural, mechanical, and outdoor applications where high torque is needed. 

Stainless steel hex bolts offer corrosion resistance, making them the best choice to use for outdoor seaside applications.

Stainless Steel Hex Bolts in a Range of Sizes

Hex bolts provide a strong and secure hold for a wide range of applications in construction and even furniture assembly. They provide high torque and convenience when applied with your coordinating torque wrench.

Stainless steel hex cap screws feature a smooth body with threading on the end. They’re typically installed using two washers and a hex nut for secure fastening.

Available Lengths 

They come in several standard thread lengths, including: 

  • For lengths up to 6" the threaded portion is → twice the diameter of the shank + 1/4".
  • For lengths over 6" the threaded portion is→ twice the diameter + 1/2".
  • Some hex caps may include an extra 1/4"–1/2" of threading, depending on the manufacturer. Please call us for exact measurements.
  • We offer diameters: up to 5/8". Larger sizes available upon request.

Weather-Resistant Hex Cap Screw Selection

Our fasteners are made from durable stainless steel, making them highly weather and rust-resistant. This makes them ideally suited for outdoor applications, such as beams, columns, and woodworking. 

We carry hex bolts in both 18-8 and 316 stainless steel. Both provide corrosion resistance for outdoor use. However, the 316 is marine-grade, offering unmatched weather-resistance in coastal areas and saltwater environments.

Uses & Benefits

  • Provide reliable clamping force for wood-to-wood, metal-to-metal, or wood-to-metal connections.
  • Anchor beams, posts, heavy timbers, and more.
  • Withstand vibration and heavy loads without loosening.
  • Corrosion-resistant stainless steel prevents rust and staining, reducing long-term maintenance.

Pro Tip: Apply an anti-seize compound or lubricant, such as WD-40, when working with stainless steel threaded rods to prevent galling and seizing.
