M39 x 220 Grade 8.8 DIN 931 Hex Head Bolts

Manufactured from Stocked Blanks

At Victory Fasteners, we recently completed the manufacture of 185 pieces of M39 x 220 Grade 8.8 DIN 931 Hexagon Head Bolts industrial fasteners for a customer requiring strict thread length tolerances and consistent quality throughout the entire production batch.

Manufactured from stocked DIN 931 Hexagon Head Bolt Blanks, the components were precision machined in-house using our CNC machining capability, allowing us to deliver a rapid turnaround whilst maintaining the exacting standards required for the application.

Precision CNC Machining

Heavy-duty fasteners often present unique machining challenges, particularly where thread length tolerances must be maintained consistently across larger production quantities.

Using our CNC machining facilities, each component was produced to the customer's specification, supported by a comprehensive quality assurance process designed to ensure accuracy and repeatability throughout manufacture.

Our machining process incorporates:

• CNC precision machining
• Automated tool wear indicators
• Strict thread length control
• Rigorous thread gauging procedures
• In-process dimensional inspection
• Final quality verification

Our automated tool wear monitoring systems continually assess machining performance throughout production, helping ensure consistent quality from the first component to the last.

Combined with stringent internal checking procedures and thread gauging, this allows us to maintain the high standards expected by customers operating in demanding industrial sectors.

Quality Built Into Every Stage

Producing high-tolerance machined fasteners relies on far more than quality machinery alone.

At Victory Fasteners, we have invested heavily in the processes, procedures and checking aids that support every manufacturing operation. From machine setup through to final inspection, each stage is controlled through documented procedures designed to deliver repeatable, reliable results.

The result was a batch of premium quality M39 x 220 Grade 8.8 DIN 931 Hex Head Bolts manufactured to specification and fully inspected before progressing to the next stage of the supply chain.

Victory Fasteners Single Source Service

Following completion of machining and inspection, Victory Fasteners arranged the customer's specified plating requirement as part of our Single Source Service.

Rather than the customer having to coordinate additional suppliers, transport components for processing, or manage multiple stages of the project, Victory Fasteners managed the process through manufacture, finishing and final delivery.

This approach helps reduce lead times, minimise unnecessary handling, simplify procurement and maintain quality throughout the supply chain.

By combining extensive stockholding, in-house machining capability, approved finishing partners, quality control and logistics support, we provide a complete engineering solution from initial enquiry through to delivery of the finished product.

Once plated to the customer's specification, the components were delivered directly to the customer, avoiding delays and eliminating the need for secondary handling.
