Custom Knurled Head Thumb Screw | Precision Machined Shoulder Screw – Stainless Steel
Custom Knurled Head Thumb Screws combine ergonomic hand-tightening with precision shoulder geometry for accurate positioning and load bearing. Manufactured from high-grade stainless steel via precision CNC machining, these fasteners feature a diamond-cut knurled head for secure grip, a precision-ground shoulder for concentric alignment and bearing surfaces, and a threaded section for secure attachment. Available in fully customizable configurations—including head diameter, knurl pattern, shoulder length, shoulder diameter, thread size, and overall length—our screws are ideal for medical devices, optical equipment, laboratory instruments, and industrial machinery where repeatable manual adjustment and precision fit are critical.
