Goebel G-Grip Lockbolt™
The best lock bolt for corrosion resistance (304 food grade stainless steel) is available at Rivet USA (this lock bolt is great for vibration resistance, too)! Available in two diameters (3/16” and 1/4″ diameters) this stainless steel bolt comes with the following head styles: Button, Truss, Rivet, or 90° Flush. The G-Grip™ achieves the following multi-grip ranges: .062-.625”, .125-.625”, and .312-1.250”. The biggest advantage the G-Grip™ offers is an extensive grip range and sizes that one G-Grip™ can replace up to 14 sizes of the classic 6-groove locking fastener systems, reducing the need to stock multiple parts for sizes. Note the Truss Head style only comes in the 1/4 “ diameter.
The G-Grip™ Lockbolt eliminates the need for a special nose tip for your Huck rivet gun as it uses the SAME nose assembly as the aluminum and steel Magnagrip huckbolts.Click to Open a Catalog Excerpt - Full G-Grip Manual

Collar Bolt™ Multi Grip
The Collar Bolt™ Multi Grip provides fast and easy light duty connection of assembled components. The Collar Bolt™ Multi Grip allows for slightly variable hole sizes and is good for using in an application with non-consistent (varying) material thicknesses. These prove great for inventory consolidation, as one Collar Bolt™ can fasten between .500” (1/2 inch) up to nearly 1.000” (1 inch)! The pin and collar design offer high shear strength and controlled clamping for fastening metal to metal. Four body diameters (3/16”, 1/4”, 5/16”, and 3/8”) are available with head styles including button, truss, flush, broad truss, or rivet heads. Each size is available in multiple grip ranges. Note, the rivet head only comes in size 3/16”, with a limited range. These sometimes are referred to as similar competitive offerings of Huck® Magnagrip® (Huck Bolt) or Avdel® Maxlok®.Click to Open a Catalog Excerpt
Collar Bolt™ Fixed Grip
The benefit of a Collar Bolt™ Fixed Grip is that they range from light to heavy duty in application (higher number = more heavy duty). Collar Bolt™ Fixed Grip series can allow for slightly variable hole sizes and is good for use in applications with a consistent material thickness. The pin and collar design offer high shear strength and controlled clamping for fastening metal to metal. Four body diameters (3/16”, 1/4”, 5/16”, and 3/8”) are available with either brazier, truss, or flush heads. Collar styles come as standard, flange or low profile for each size. Collar Bolts™ come in steel, aluminum (2024 or 6061), and stainless steel, with a steel grip. Note, the flange collar has the widest range of head height and diameter. These sometimes are referred to as similar competitive offerings of Huck® C6L, C50L or C120L (HuckBolt) or Avdel® Avdelok®.Click to Open a Catalog Excerpt
