Screw & wall plug kit Fischer 503784 100 mm 4 pcs

The Fischer 503784 screw & wall plug kit contains four 100 mm anchors designed for secure fixing in brick and concrete. Each anchor requires a 10 mm drill hole diameter and a minimum embedment depth of 110 mm. Certified to ETA-07/0121, the anchors are intended to deliver consistent mechanical performance for a range of fastening tasks in construction and renovation projects.

Advantages

This screw and wall plug kit offers durable load-bearing capacity in solid masonry and concrete substrates and consistent expansion characteristics that ensure stable anchorage. The 100 mm length provides deeper grip for thicker fixtures, and the kit format with four pieces is convenient for small installation jobs or repairs. ETA certification confirms that the anchors meet specific European technical assessment criteria for predictable behavior under load.

• Quantity per kit: 4 pieces
• Certification: ETA-07/0121 (European technical assessment)

How to use

Drill a hole with a 10 mm diameter to a depth of at least 110 mm in the intended masonry or concrete surface. Clean the hole of dust and debris before inserting the wall plug. Insert the anchor fully until flush with the surface, then drive the screw to expand the plug and achieve the required clamping force. Follow standard installation practices for spacing and edge distances according to the fixture load and substrate condition.

Usage recommendations

Use a hammer drill with a masonry bit for efficient drilling in concrete or brick. Verify substrate condition and maintain recommended spacings and edge distances to avoid splitting or reduced load capacity. For critical or safety-related applications consult relevant design guidelines or a structural engineer to determine appropriate embedment and anchor layout.
