THE COMPANY
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.
A bank of CNC machining centers are
employed at ARP to perform specialty
operations.
Contemporary EDM
technology is used to
perform special operations,
such as hex-broaching
the nose of a unique
short-run fastener.
Fasteners are shot-peened after heat-treatment to improve overall
external integrity.
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.”
