Medical Laboratory Testing: Bolt Pull Out
Bolt Pull Out testing measures the force required to extract a bolt or screw from its substrate or bone simulant. The test applies axial tension until failure and records the peak load and failure mode. For medical manufacturers, high pull-out strength is essential for orthopedic screws, bone plates, anchors, and fixation devices to ensure secure attachment and resistance to loosening under physiological loads.
Secure fixation is critical in orthopedic and trauma applications. A fastener with poor pull-out strength can lead to implant loosening, delayed healing, or the need for revision surgery. Applus+ Reliable Analysis already maintains accredited mechanical testing capabilities, including pull-out strength, integrated with our hardness, impact, and failure analysis programs.
These evaluations support material and device qualification for implants and fixation systems. Manufacturers use bolt pull-out data to verify design performance, material selection, and compliance with regulatory standards. Applus+ Reliable Analysis delivers accurate, reproducible results using equipment already operating daily under our ISO/IEC 17025 accreditation.
Common Bolt Pull Out Medical Testing Standards
ASTM F1144 Tension, Torsion, and Bending of Bone Plates and Screws
ASTM F1144 includes requirements for bone plates and screws, with pull-out strength as a key mechanical performance metric. The standard evaluates how well screws resist axial pull-out forces in plated constructs. It is widely used for orthopedic fixation systems to ensure stable bone-plate-screw assemblies that can withstand physiological loads without loosening or failure.
ISO 6475 Implants for Surgery Metal Bone Screws
ISO 6475 specifies dimensions and performance requirements for metal bone screws, including pull-out strength evaluation. The standard ensures screws provide adequate fixation strength in bone. It is essential for metallic bone screws used in orthopedic and trauma applications to verify mechanical performance and compatibility with plating systems.
ASTM F543 / ISO 10993-18 Biocompatibility and Mechanical Integrity
ASTM F543, when combined with ISO 10993-18, links mechanical pull-out strength with chemical characterization to assess whether fixation devices maintain integrity without releasing harmful substances. The approach supports comprehensive evaluation of implants and screws for both mechanical fixation and biocompatibility.
ASTM F1174 Mechanical Pull Out Testing of Bone Anchors
ASTM F1174 provides a practice for mechanical pull-out testing of bone anchors and similar fasteners. The standard measures the force required to dislodge the anchor from bone or a test substrate. It is valuable for evaluating suture anchors, soft tissue fixation devices, and other medical fasteners to ensure reliable anchorage under tensile loads.
