Our nylon slotted grub screws feature a headless design with a straight slot drive, allowing for flush or recessed installation using a flat-bladed screwdriver. Conforming to DIN 551 specifications, they are typically used in applications requiring secure axial positioning of components without protruding hardware, making them ideal for compact assemblies and surface-sensitive systems.
Applications
Nylon slotted grub screws are frequently used in fine mechanical systems, electronics, and laboratory instruments. Their non-conductive, non-magnetic properties make them highly suitable for securing shafts, collars, and rotating parts in electrical or RF-sensitive equipment. These fasteners are often specified in adjustment points or calibration mechanisms in optical, medical, and metrology devices, where minimal thread damage and repeatable load control are essential.
Their usage includes lightweight structural assemblies, insulating hardware for PCB mounting, and plastic-to-plastic fastening, where their chemical resistance and low abrasion characteristics help maintain long-term reliability. They deliver excellent mechanical strength, low water absorption, and dimensional stability across a broad temperature range. These screws also exhibit good resistance to oils, fuels, and most industrial solvents, making them suitable for demanding environments.
Whether your system requires a lightweight locking component, a corrosion-proof positioning screw, or an electrically neutral adjustment point, HPP’s nylon slotted grub screws offer an engineered solution for technical and specialist fastening applications.
