Draadanker Fischer RG M 20 x 260

The Fischer RG M 20 x 260 threaded anchor is a steel expansion anchor with a silver finish, designed for secure fastening in solid substrates. With an overall length of 260 mm and a nominal diameter of 20 mm, it is intended for use in drill holes of approximately 25 mm. Supplied as a single unit, this anchor provides a durable mechanical connection for heavy-duty fixtures where reliable load transfer is required.

Advantages

The steel construction ensures high tensile strength and resistance to deformation under load. The expansion mechanism generates firm contact with the base material, delivering stable performance in concrete and other solid masonry. Its silver finish offers basic corrosion resistance and a consistent appearance for visible fixings. Single-piece packaging allows selection of the exact quantity needed for both professional and DIY tasks.

Suitable for

• Heavy-duty fixation of structural elements to concrete and solid masonry
• Mounting rails, brackets and support profiles
• Securing machinery bases, handrails and stair stringers
• Applications requiring a long embedment depth for increased load capacity

Key specifications

• Material: steel
• Finish: silver
• Nominal thread size: M20
• Overall length: 260 mm
• Recommended drill hole diameter: 25 mm
• Packaging: single unit

How to use

Drill a hole with the specified diameter to the required depth, taking care to remove dust and debris from the hole before installation. Insert the threaded anchor into the hole until the required embedment depth is reached. Tighten the fixture nut or bolt to the recommended torque to expand the anchor and achieve secure contact with the base material. Verify correct seating and tighten progressively to ensure uniform expansion.

Recommendations

Use this anchor in solid concrete or solid masonry only; avoid hollow or weak substrates unless additional measures (such as resin or sleeve anchors designed for hollow material) are taken. Ensure drill holes are clean and that the anchor length and embedment meet load requirements. For outdoor or corrosive environments, consider stainless steel or specially coated anchors for enhanced corrosion resistance.
