Steel Bolts – Strong, Reliable Connections

Steel Bolts for Framing Projects
These standard steel bolts are the backbone of any T-slot build. Made from strong steel and often zinccoated, they resist rust and give you secure fastening in structural aluminium frames.

Button Head Bolts (M4 & M8)
If a sleek finish matters, the button head bolts offer a smooth, domed cap that complements modern T-slot designs.

• M8 Button Head Bolt, Steel: A medium-duty option especially suited to T-slot joints
• M4 x 12mm Button Head Socket Cap Screw: Compact, clean, and versatile for smaller builds.

Countersunk Steel Bolts
For flush mounting where protrusions are unwanted, countersunk steel bolts are the go-to choice. They nest neatly into the extrusion groove with a low profile.

How to Choose the Right Fastener

1. Assess the Load Requirements
Heavy frameworks like workbenches or robots demand steel M8 bolts. Lighter structures or display units may only need M4 button head screws.

2. Factor in Environment
For outdoor setups or damp areas, opt for stainless steel bolts and T-slot nuts resistant to rust and corrosion.

3. Consider Aesthetics
If you want a minimal, tidy appearance, go for countersunk bolts. Button head bolts offer a more decorative alternative without sacrificing strength.

Simple Installation Steps

• Slide a T-slot nut into the extrusion groove at the desired position.
• Align your bracket, panel, or connector.
• Insert the steel or stainless bolt through the component and into the nut.

Tighten to secure. Adjustability remains effortless—loosen, slide, and retighten as needed.
