The innovative screw anchor for interior and exterior concrete and masonry The MULTI-MONTI®-plus A4 (MMS-plus A4) screw anchor is a further development of the MULTI-MONTI® A4 concrete screw. It is screwed directly into a pre-drilled hole without a plug and can be loaded immediately. The reinforced toothing on the screw tip cuts an internal thread into the building material when it is screwed in. This creates a positive fit, which is ultimately used for anchoring. This not only simplifies the installation process, but also guarantees the craftsman a high degree of application safety. The MULTI-MONTI®-plus A4 concrete screw can be used close to the edge without a torque spanner and can be completely removed.Product benefits MMS plus:The screw anchor with maximum installation convenienceOptimised concrete thread for powerful anchoringUp to three setting depths for more flexibilityExpanded product range for more applicationsVersion in stainless steel A4 1.4401, stainless steel 1.4529 / HCR on requestPhosphated functional tip for safe undercutting of the concreteApproved and monitored product for cracked and non-cracked concreteEuropean Technical Assessment: ETA 15/0784Shape: MMS plus -Ftfix Useful length max.(mm): 35d1(mm): 7.5Brand: HecoDrill ø(mm): 6Surface: A4L(mm): 75h1 Drilling depth(mm): 60Material: Stainless steelSize(mm): 7.5x 75Head ø(mm): 13.6hnom1 Anchoring depth(mm): 55tfix Usable length min.(mm): 20hnom2 Anchoring depth(mm): 40Thread length(mm): 59Drive: TX30Content specification (ST): 50.
