2014 ARP Catalog

A bank of CNC machining centers are employed at ARP to perform specialty operations.

THE COMPANY

Contemporary EDM technology is used to perform special operations,

Also on the premises is a fully-equipped lab for R&D and quality control. It has everything required to ensure that ARP products measure up to the company’s ultra high standards. Some of the tests that ARP personnel perform on a daily basis include proof loading (using a 120,000 lb. capability tensile machine), fatigue cycle (Amsler) and hardness (Rockwell). Visual inspections include use of an optical comparator (to check thread root contour, etc.), fixtured micrometers and microscopic grain flow analysis. The computer-controlled fatigue cycle testers allow ARP to take fasteners to a failure point in millions of cycles – as opposed to the aerospace norm of 65,000 average to 130,000 cycles maximum. This allows ARP engineers to verify the design specifications of each fastener, and prove its ability to provide superior long-term service. Finished products are packaged and warehoused in ARP’s Ventura facility, which is also home to the firm’s customer service, technical and sales office.

such as hex-broaching the nose of a unique short-run fastener.

ARP’s popular stainless steel engine & accessory fasteners are polished to a brilliant luster using this specialized equipment.

The finishing touch for most chrome moly fasteners is the black oxiding operation. Fasteners go through a series of “baths.”

Fasteners are shot-peened after heat-treatment to improve overall external integrity.
