Shoulder Bolts: Custom-Engineered Solutions for High-Precision Applications

Engineered for Precision  Alignment, Movement, and Mounting

Shoulder bolts also known as stripper bolts are specialty fasteners with a precision-machined shoulder separating the head from the threaded portion. This geometry allows them to function as guides, pivot points, mounting pins, or axles within mechanical assemblies that demand repeatable alignment and smooth motion.

Customization and Manufacturing Methods

At G-Fast Distribution, we provide shoulder bolts engineered to exacting tolerances. Whether cold-headed, hot forged, or machined from bar, each part is evaluated for performance, process capability, and manufacturability under our FASTENEERING® methodology.

Custom and Standard Shoulder Bolts for Industrial Use

Shoulder bolts, also known as stripper bolts, are a specialized type of fastener designed with an unthreaded shoulder between the head and threaded portion. This unique design allows them to function as pivot points, axles, guides, or mounting pins in precision assemblies. At G-Fast, we supply high-quality shoulder bolts engineered for durability, consistency, and reliability across a wide range of applications. General Key Features
  • Design: Precision-machined shoulder for accurate alignment and spacing.
  • Material Options: Available in stainless steel, alloy steel, and carbon steel for superior strength and corrosion resistance.
  • Sizes & Dimensions: Offered in a variety of diameters, shoulder lengths, and thread types to meet diverse requirements including inch and metric Left-Hand-Threads.
  • Threading: Rolled or cut threads for secure fastening and smooth assembly.
  • Finishes: Optional coatings and plating to enhance wear resistance and extend service life

Benefits of Choosing Custom Shoulder Bolts

While standard options meet many needs, custom shoulder bolts provide the exact solution designed to perform as intended, including performance advantages:
  • Tailored Fit: Designed to exact specifications for unique applications
  • Enhanced Durability: Optimized material and finish selection to suit environmental conditions
  • Improved Performance: Reduced wear, and friction in high-precision assemblies
  • Cost Efficiency: Long-term savings through replacement repeatability with reduced downtime
 Applications Across Industries Shoulder bolts are critical components in industries where precision and strength are essential. Common applications include:
  • Aerospace: structural assemblies, and testing equipment
  • Industrial Machinery: Robotics, conveyor systems, linear motion and production equipment
  • Material Handling: Pivot points on arms, moving control equipment
