Fastener Solutions Developed for Your Specific Requirements

Our quality-assured global sourcing services allow us to strategically supply available fastening solutions from both domestic and international sources. And these sourcing capabilities extend beyond standard fasteners and can include specialty products, bottlenecked items, and hard-to-source fasteners. For many of our customers, we manage all aspects of the supply chain — from analysis and negotiation to procurement and testing, to delivery and inventory monitoring.

It is important to note that our fastener solutions are not limited to a standard inventory of fastener types. Using the capabilities of our custom manufacturing arm, APTP, we can accommodate both low- and high-volume fastener production requirements. In addition, we can also provide specialty machined parts to exact specifications.


Quality Assurance

Within our on-site A2LA-accredited Quality Assurance Testing Lab, our team tests fasteners and related parts to ensure that the products we manufacture, stock, and distribute meet the strictest customer quality requirements.

Working with our petrochemical specialists and manufacturing teams, our quality testing group ensures that all customer requirements and per-spec designs, materials, and finishes are accurately met.
