FAMILY / 01
Bolts
Close-tolerance, high-strength bolts in twelve-point, hex, spline, flush and shear head configurations — including fatigue-rated parts for primary structure.
Sylmar, California · CAGE 4GP55 · AS9100D
We make the bolts that hold flight hardware together.
Acufast forges, grinds, turns, rolls and tests high-strength externally threaded fasteners to AS, MS, NAS and AN standards — plus built-to-print parts — from a 55,000 sq ft floor north of Los Angeles.

What we build
Three product families, one thread form
Everything we make is externally threaded and destined for a joint that cannot come apart. Manufactured to AS, MS, NAS and AN standards, or built to your print.
FAMILY / 02
Pins & studs
Ground and turned pins, shear pins and threaded studs held to tight diameter and straightness limits, with drilled and slabbed features as required.
FAMILY / 03
Specialty fasteners
Built-to-print hardware with non-standard heads, hybrid features or unusual alloys — the parts other shops quote long and deliver late.
Under one roof
From bar stock to certified part
Every operation below happens in our building. Nothing waits in a truck between steps, which is why our lead times hold when a program schedule moves.
OP 10
Hot forging
Heads formed on hot presses to develop grain flow where the part carries load.
OP 20
Centerless grinding
Shank diameters brought to size and roundness ahead of thread rolling.
OP 30
CNC turning
Profiles, undercuts, tapers and specialty geometry cut on CNC lathes.
OP 40
Thread rolling
Threads rolled rather than cut, for a compressed root and better fatigue life.
OP 50
Secondary operations
Drilling, slotting, slabbing and the rest of a complete secondary department.
OP 60
Part marking
Full marking capability including laser marking for traceability requirements.
OP 70
Test & inspect
In-house destructive lab and Nadcap-approved NDT lab close the loop before shipment.

Departments
OP 10
Forging
Hot presses form the head and set grain flow before anything is cut.
OP 20
Grinding
Centerless grinders bring shank diameters into tolerance and round.
OP 30
CNC turning
Undercuts, tapers and the geometry that makes a part specialty.
Test & inspection labs
NDT · Nadcap
Fluorescent penetrant
Surface-breaking indications glow under UV before a part leaves the building.
NDT · Nadcap
Magnetic particle
Ferrous alloy verification under our approved non-destructive testing scope.
Destructive
Tension, shear, fatigue
Stress rupture to 22,000 lbs, tension and shear to 400,000 lbs, plus fatigue.
