Custom Aluminum Alloy Knurled Handle Bolt 12.8×25mm Lightweight Threaded Grip Fastener

Product Description:
This knurled aluminum handle bolt measures 12.8mm in diameter and 25mm in height. It is produced from pure aluminum using high-precision CNC turning technology. The result is a reliable, lightweight fastener with clean threading and an elegant appearance, perfectly suited for manual operations and tool-free adjustments.

The external surface features a conical top and fine vertical knurled lines, enhancing friction during gripping and preventing slipping in repetitive use. This structure ensures stability during frequent tightening or loosening without the need for additional tools. The standard finish is raw aluminum, but customization for color anodizing or matte sandblasting is available upon request.

The component is widely used in various mechanical assemblies such as control panels, test fixtures, lightweight equipment structures, and enclosures in electronics or automation fields. Thanks to the aluminum material, it offers excellent balance between weight, strength, and corrosion resistance.

We support custom processing for dimensions, internal threads (metric/inch), and surface finish options. ISO9001-certified production and strict inspection standards ensure high consistency for every batch. We also provide packaging customization, logo engraving, and sample delivery upon request.
