Expansion Bolt Baks E90 SRB M6×30mm – metal anchor fastener

Baks E90 SRB M6×30mm expansion bolt is a metal anchor fastener engineered for secure fixing in solid base materials. The anchor combines a threaded M6 stud with a 30 mm shank length and a mechanical expansion sleeve that engages when tightened, creating a reliable hold in concrete, solid brick and similar substrates. This compact, threaded anchor is intended for fastening fixtures, brackets and light fittings where a dependable, low-profile metal anchor is required.

Advantages

The expansion bolt provides strong mechanical expansion and uniform load distribution in solid materials. Its metal construction offers durability and resistance to deformation under torque. The compact M6×30 mm size allows installation in confined spaces while still delivering stable pull-out performance for light to medium loads. The threaded design simplifies fitting and removal of fixtures without damaging the base material.

Suitable for

• Fixing brackets and supports to concrete or solid brick walls
• Mounting light fittings, pipes and conduit clamps
• Securing fixtures in renovation and repair work
• Attaching hardware where a compact, threaded metal anchor is needed

Key specifications

• Anchor type: metal expansion bolt with mechanical sleeve
• Thread size: M6
• Shank length: 30 mm
• Suitable base materials: concrete, solid brick, similar solid substrates
• Installation method: torque-induced mechanical expansion
• Application load range: designed for light to medium loads (fixture fastening)

How to use

Drill a hole in the base material to the diameter and depth recommended for an M6 expansion bolt. Clean the hole of dust and debris before insertion. Insert the expansion bolt so the sleeve sits flush with the substrate surface, then tighten the nut or bolt head to the specified torque. As the fastener is tightened, the sleeve expands against the hole wall, creating mechanical anchorage. Verify alignment of the fixture while tightening and recheck torque after initial setting.

Usage recommendations

Use appropriate drill bits and follow base material guidelines to ensure correct hole diameter and depth. For load-critical or safety-related applications, consult relevant standards or an engineer to confirm suitability and required edge and spacing distances. Avoid use in hollow or weak substrates; select a different anchor type for cavities or perforated blocks.
