Description
ISO 8752 304 Stainless Steel Plain Slotted Roll Pins
Product Overview

ISO 8752 65Mn Black Oxide Slotted Spring Pins (also known as roll pins or tension pins) are self-retaining, headless, hollow mechanical fasteners with a continuous slot down the center. Engineered from premium 65Mn high-carbon spring steel, these pins feature double-end chamfers for effortless insertion into drilled holes.

When driven into a hole slightly smaller than the pin's relaxed outer diameter, the pin contracts, applying continuous outward radial compression against the inner wall. This spring action provides superior friction resistance, preventing movement, shear displacement, and loosening caused by high vibration.

Key Features & Advantages
  • High-Grade 65Mn Spring Steel: Offers superior yield strength, fatigue endurance, and dynamic tension compared to standard carbon steel pins.
  • Black Oxide Finish: Provides micro-layer corrosion protection, enhanced surface lubricity for smooth installation, and an industrial matte-black appearance.
  • Vibration-Proof Self-Locking: Eliminates the need for secondary reaming, threading, or locking devices, saving production cost and assembly time.
  • Double-End Chamfered Design: Ensures self-centering alignment for precise automated or manual installation.
Industrial Applications
  • Automotive Industry: Gearbox linkages, shift forks, steering shafts, and brake linkages.
  • Industrial Machinery: Power transmission shafts, gear connections, drive pulleys, and conveyor assemblies.
  • Agricultural Equipment: Heavy-duty tractor linkages, implements, and harvester mechanisms.
  • Tooling & Manufacturing: Stamping die positioning, jig holding, and motor shaft retention.
Frequently Asked Questions
Q1: Why select 65Mn spring steel instead of stainless steel?
A: 65Mn spring steel offers significantly higher tensile yield strength, elasticity, and shear resistance, making it superior for heavy loads and continuous shock vibration applications.
Q2: What are the primary benefits of the Black Oxide surface treatment?
A: Black oxide adds corrosion protection without altering dimensions, eliminating thread/hole distortion risks associated with thick coatings.
Q3: Can these slotted spring pins be reused?
A: Yes, due to the high elasticity of heat-treated 65Mn steel, these pins retain their outward tension force and can be re-installed multiple times.
