Ruuvi Fischer 536863 120 mm 50 kpl

Fischer 536863 120 mm screws are metal fasteners engineered for anchoring into concrete and other solid substrates. Supplied in a box of 50 pieces, each screw has a 120 mm length suited to medium-depth fixing tasks. The screws are intended for general utility applications where a reliable, robust connection to masonry is required, and they are compatible with typical power screwdrivers or impact drivers used in construction and renovation work.

Advantages

These concrete screws offer consistent thread engagement and strong pull-out resistance when installed in appropriate substrates. The 120 mm length provides sufficient embedment for secure fixtures while the box quantity of 50 ensures continuity of work without frequent replenishment. Machined threads and a durable surface finish contribute to long-term mechanical stability and ease of installation with standard drive bits.

Suitable for

• Fixing medium-weight fixtures to concrete and masonry
• Installing brackets, rails, and support plates
• Renovation and repair work in residential and commercial buildings
• Temporary and permanent installations requiring mechanical anchorage

Key specifications

• Length: 120 mm
• Pack quantity: 50 pieces
• Material: steel (surface treated for durability)
• Head type: suited for standard driver bits (cross or slotted depending on variant)
• Application substrate: concrete and masonry

How to use

Select an appropriate drill bit and pilot hole depth corresponding to the screw length and substrate. Drill the pilot hole to the recommended diameter, clean out drill dust, then position the screw and drive it using a power screwdriver or impact driver until the head is flush with the fixture. Ensure the screw achieves full embedment into the concrete without over-torquing; follow general mounting guidance for concrete fasteners to achieve optimal holding values.

Recommendations

Verify substrate condition and select the correct pilot hole diameter for concrete to ensure proper anchorage. Use personal protective equipment when drilling and installing. For load-critical or seismic applications, consult relevant technical documents and engineering guidance to confirm suitability.
