Miscellaneous Capabilities

Welding

Portland Bolt employs certified welders to perform light fabrication and welding of custom fasteners and anchor bolt assemblies.

Chamfering/Pointing

Many bolts require a chamfering operation which is the beveling of the end of a bolt (removal of the first thread) to facilitate easy installation of a nut. Bolts used for wood applications often require a semi-cone point to allow easy installation of the fastener through the wood members. Lag bolts require a cone point for screwing into wood. These operations are performed with highly specialized equipment designed to quickly and consistently apply various degrees of points to fasteners.

Stamping

Under ASTM specifications, most high-strength rods and anchor bolts require permanent grade identification and the manufacturer’s registered logo to be stamped on one end. Portland Bolt uses hydraulic stamping equipment to permanently identify high-strength products.

Swedging

Swedging is a process in which indentations are placed in the unthreaded end of an anchor bolt which is to be embedded in concrete. We use specialized hydraulic swedging equipment to produce these parts. Different engineering firms and State Departments of Transportation have very specific requirements regarding the size, depth, and placement of the indentations. Portland bolt can accommodate any special swedging requirements.
