The PrecisionGeek M6 x 10mm Shoulder Thumb Screws are designed for reliability, ease of use, and precise alignment. Crafted from blackened steel, these hand-tightening screws feature a machined shoulder for applications requiring consistent spacing and load distribution—ideal for technical fixtures, speaker mounting, and custom equipment. Their ergonomic grip allows for tool-free installation and adjustments, making them a great solution for DIY, workshop, stage tech, or audio builds. The blackened finish not only adds corrosion resistance but also gives a professional, low-reflection appearance. Manufactured in the EU, these screws meet high standards of accuracy and performance in demanding environments. Thumb screws are designed to be tightened and loosened by hand. Large head diameter makes it easy to access and tighten. The thumb screw has a diamond knurled surface on its head. This gives it better gripping surface, making it easier to tighten or loosen the fastener manually. ------------------------- PrecisionGeek are very proud that our stainless steel and aluminium fittings are all made in-house on our own Star CNC Machines.
