Screw & wall plug kit Fischer 503782 140 mm Torx 4 pcs

The Fischer screw & wall plug kit 503782 contains four heavy-duty anchor sets with 140 mm length screws designed for secure fixing in solid masonry such as brick and concrete. The kit pairs long anchor sleeves with Torx-head screws to provide reliable load transfer and improved hold in deep drill holes. Drill hole diameter is 10 mm and the recommended minimum drill depth is 150 mm, making this kit suitable for demanding installation tasks where long-reach anchors are required.

Advantages

Long 140 mm anchors offer increased embedment depth for higher pull-out resistance in solid substrates. The Torx screw head ensures positive driver engagement, reducing cam-out and allowing controlled torque application during installation. The components are matched for consistent performance in masonry, delivering stable fixing for structural and non-structural applications.

Suitable for

• Fixing heavy fixtures to brick and concrete walls
• Mounting rail systems, brackets, or supports in masonry
• Installations requiring deep embedment for higher load capacity
• Outdoor and indoor construction applications where solid substrates are present

Key specifications

• Anchor length: 140 mm
• Screw head type: Torx
• Quantity: 4 pieces
• Recommended drill hole diameter: 10 mm
• Recommended minimum drill depth: 150 mm
• Suitable substrate: solid masonry (brick, concrete)

How to use

Mark the fixing points, then drill a 10 mm diameter hole to a minimum depth of 150 mm in the masonry. Clean the hole of dust and debris before inserting the anchor sleeve fully into the hole. Position the fixture and drive the Torx screw through the fixture into the anchor until the sleeve expands and secures against the substrate. Apply torque appropriate for the screw size and the fixture weight, avoiding overtightening.

Usage recommendations

Use a hammer drill for clean holes in brick and concrete, and always check substrate condition and load requirements before installation. For vibration-prone or dynamic loads consider specifying anchors with measured dynamic performance and follow local building regulations for safety margins.
