Weld Nuts, Weld Bolts, Weld Pins & Weld Studs

An extensive range of Weld Nuts, Weld Bolts, Weld Pins and Weld Studs are available from stock, or manufactured to our customer’s specific design specification.

At Crown Screw we understand the critical role that our fasteners play in the manufacture of your products. From high volume automotive customers, local fabricators to low volume prototyping, we will have the precise components for your requirements. This information page is designed to give you a brief overview into the world of weldable fasteners, to guide you towards the right component for your project.

Weld Nuts

Weld nuts provide a fast, efficient and cost-effective way to fix nut to sheet fabrication, enabling a female threaded body to be permanently attached ready for further assembly processes. Due to the projection or spot-welding process, you can expect to see high torque values that are suitable for heavy duty fixing. Most commonly used in the automotive pressing and fabrication industry, they are available in various thread sizes, strengths, materials and finishes. If a special is required, we can manufacture to your specific requirements.

Range: Square DIN928, Hexagon DIN929, Standard and Deep Collar Hexagon, Hexagon Flange, Locking, JIS (Nissan/Toyota), Spit Trap, Unthreaded and Slab Base Weld Nuts

Threads: Metric, Imperial, Oversize

Strength Class: 4, 6, 8 and 10

Materials: Steel, Stainless Steel, Aluminium

Finishes: Self Colour, Zinc, Copper, Nycote PTFE Thread Masking.

Weld Bolts

Weld bolts provide a fast, efficient and cost-effective way to fix a bolt to a sheet fabrication, enabling a male threaded stud to be permanently attached ready for further assembly processes. Due to the projection or spot-welding process, you can expect to see high torque values that are suitable for heavy duty fixing. Most commonly used in the automotive pressing and fabrication industry, they are available in various thread sizes, strengths, materials and finishes. If a special is required, we can manufacture to your specific requirements.

Weld Pins

Weld pins provide a fast, efficient and cost-effective way to fix a pin to a sheet fabrication, enabling a male unthreaded stud to be permanently attached ready for further assembly processes. Due to the projection or spot-welding process, you can expect to see high torque values that are suitable for heavy duty locating and fixing. Most commonly used in the automotive pressing and fabrication industry, they are available in various diameters, strengths, materials and finishes. If a special is required, we can manufacture to your specific requirements.

Range: BS7670, Ford, Nissan and Toyota Specifications

Tensile Strengths: 4.6, 4.8, 8.8, 10.9 and 12.9

Weld Studs:

Weld studs provide a fast, efficient and cost-effective way to fix a stud to a sheet fabrication, enabling a male threaded stud to be permanently attached ready for further assembly processes. This range of studs is ideal for arc welding processes, generally but not exclusively in thin gauge material. Most commonly used in the automotive pressing and fabrication industry, they are available in various thread sizes, strengths, materials and finishes. If a special is required, we can manufacture to your specific requirements.
