Detailed Description
Overview
Our Black Oxide Flat Head Clevis Pins are industrial-grade cylindrical fasteners designed for rotational hinges, pivot points, and mechanical linkages. Manufactured strictly to DIN 1444 (Form B) and ISO 2341 standards, these pins feature a flat, low-profile head on one end and a precision cross-drilled hole on the opposite end to house cotter pins or R-clips.
The black oxide treatment not only provides a sleek, dark aesthetic and reduced glare, but also retains lubricating oils to reduce friction and improve wear resistance in high-cycle machinery applications.
Key Features & Advantages
- High Precision & Low Tolerances: Machined to exact shaft dimensions for smooth insertion and minimal play in critical joints.
- Non-Reflective Black Oxide Finish: Ideal for applications requiring anti-glare properties, clean dark aesthetics, or oil-retaining surfaces.
- Burr-Free Cross Hole: Chamfered entry hole prevents damage to cotter pins and speeds up manual assembly.
- Exceptional Shear Strength: Available in medium carbon steel (45# / 1045) and alloy steel with optional heat treatment for heavy-duty load conditions.
