About Flexible Assembly Systems

We sell it. We calibrate it.

What we supply, and what we do after the sale.

01Torque tools and controllers0.16 – 200 Nm+

We supply torque screwdrivers, nutrunners, torque wrenches, and programmable controllers to manufacturers across North America, spanning precision drivers for electronics assembly through industrial bolting.

Shut-off type usually matters more than brand. Click wrenches signal the operator and rely on them stopping; cam-over drivers mechanically disengage so an inattentive operator cannot overtighten; transducerized tools measure the joint in real time and report torque and angle to a controller.

  • Electronics · 0.16–1 NmESD-safe precision drivers
  • General assembly · 1–50 NmElectric and pneumatic screwdrivers
  • Structural · 50–200 NmImpact and pulse tools
  • Industrial bolting · 200 Nm+Multipliers and hydraulic wrenches
02Automation and robotic cellsEngineered to order

Beyond individual tools, our engineers scope and build robotic screwdriving, dispensing, inspection, and finishing cells. Screw feeders, vision systems, and torque verification are integrated so the station reports every cycle rather than assuming it.

Most projects start the same way: a station a person is doing today, a cycle time it has to hit, and a defect that keeps escaping. We work back from those three numbers to a design.

  • Robotic screwdrivingFeeder, driver, and verification in one cell
  • Adhesive and sealant dispensingRepeatable bead paths
  • AI vision inspectionCatches the defect at the station
  • Grinding and polishingConsistent finish without fatigue
03Calibration, certification, and repairISO 9001:2015

Our ISO 9001:2015 calibration department certifies and repairs torque tools — including tools bought elsewhere — against traceable standards, with documented as-found and as-left readings on every certificate.

The as-found reading is the one that matters for a quality system: it tells you whether the tool was in spec while it was building product, which is the question an auditor actually asks.

  • Standard interval12 months or 5,000 cycles
  • High-duty or safety-criticalCommonly 6 months
  • After any drop, overload, or repairRecalibrate first
  • Certificates stay downloadable for audits
04Material handling and liftingBuilt to order

Hoists and actuators are configured to capacity, lift height, headroom, and voltage. Many are built to order and quoted the same day, with spare parts stocked for equipment already in service.

Four numbers determine almost every hoist quote. Gather these before calling and the quote usually comes back the same afternoon.

  • CapacityRated load, including the fixture
  • LiftHook travel from lowest to highest position
  • HeadroomDistance between beam and hook
  • PowerAir supply, or voltage and phase
05Buying on terms, quotes, and volume pricingNet terms

Approved accounts buy on purchase orders with net terms, volume schedules for repeat lines, and support for government and military purchasing. Apply once and your team orders against a PO.

Configured and specialty items are quoted rather than priced, because a hoist built to a 29 ft lift and one built to a 12 ft lift are genuinely different parts.

  • Request a quoteConfigured and engineered items
  • Contract pricingRepeat lines and multi-site rollouts
  • Free freightWeb orders over $999.99 on stocked items

Asked weekly. Answered here.

A.

Open the order in your account's purchase history and click Request a Return. A representative issues a Return Authorization (RMA) number within 24–36 hours; ship the item back within 14 days of the RMA with the number on the package. Non-defective returns may carry a 25% restocking fee.

A.

Log in and open My Account to see the current status of every order. If the status isn't clear online, customer service can look it up by phone, email, or live chat.

A.

Yes — contact us by phone, email, or live chat as soon as possible. Orders already released to the warehouse or shipped direct from the manufacturer may have to be handled as a return instead.

A.

Following the 2018 Supreme Court ruling on online sales, we collect tax where state and local law requires it — currently orders shipping to Arizona, California, Nevada, and Washington. Resale certificates can be applied to your account for tax-exempt ordering.
