A simple four-step service.
Bradley is a customer-supplied fastener coating service. You ship the parts, we apply the chemistry to spec, and we ship the coated parts back — ready to be used in production.
INQUIRY
Quote
Send your fastener spec, OEM cross-reference, or sample part. We return pricing per thousand pieces and a lead-time confirmation, typically within hours.
SHIPMENT IN
Ship Fasteners
You ship clean, dry, uncoated fasteners to our St. Charles, IL service center. We don’t sell or stock fasteners — you supply, we apply.
COAT
Pre-Apply
We apply Loctite Dri-Loc, PRECOTE, Bradley Nylon Patch, Tec-Flon, or other specified chemistry under ISO 9001:2015. Full QA documentation ships with every order.
SHIPMENT OUT
Production-Ready
Coated parts ship back to your dock with certifications, ready to go straight to your customer’s assembly line.
Why companies use pre-applied threadlockers.
Liquid thread-lockers applied at the assembly bench introduce variables: operator technique, dosage, waste, inconsistent applications. Pre-applied chemistry — cured onto the fastener in advance — removes those variables before the bolt reaches the line.
Faster assembly
No bottle. No brush. No timing. The operator picks up the bolt, threads it in, and torques it down. Cycle time drops; production increases.
Repeatable quality
Every fastener receives the same dose, applied in a controlled environment with full lot traceability. No more “the second-shift guys put too much on.” Consistent application every time.
Spec compliance
Pre-applied chemistries are specified by name in most OEM standards (GMW3359, Ford WSS-M99P, etc.). Bradley applies to the issuing OEM’s standard.
Clean workstation
No bottles. No wet rags soaked with expensive materials. No solvent wipes. Pre-applied keeps the assembly cell — and the operator’s gloves and station — clean.
Vibration resistance
Anaerobic chemistries cure to a tough polymer between the threads when assembled, eliminating the gaps that vibration normally exploits.
Inventory simplicity
One pre-coated SKU replaces a fastener + adhesive bottle + applicator + training program. Distributors carry one part number, not three.
Liquid vs. pre-applied: where the math lives.
The two columns below are how most distributors frame the cost story to an OEM end user. The savings are largest at higher production volumes, but they show up in any assembly cell.

SHOP-APPLIED · PER ASSEMBLY
- ×Per-bolt time: 4–8 seconds for application, plus operator hesitation while the dose lands.
- ×Wasted chemistry: a significant portion of dispensed adhesive is wasted through over-application, drips, and bench contamination — none of which happens with pre-applied.
- ×Inventory burden: bottles, applicators, spare nozzles, solvent wipes, gloves, MSDS binders.
- ×Operator training: dosage technique, cure time, environmental sensitivity.
- ×Quality variability: every shift produces a slightly different joint.
- ×Rework risk: under-dosed bolts loosen in service; over-dosed bolts contaminate adjacent components.
Pre-applied from Bradley
FACTORY-APPLIED · READY TO USE
- ✓Per-bolt time: zero seconds added to the assembly cycle. The operator picks, threads, torques.
- ✓Dose precision: the entire applied coating is on the thread, in a controlled-environment shop, with QA inspection.
- ✓Inventory simplicity: one pre-coated SKU replaces bottle + applicator + training.
- ✓No bench training: there’s nothing for the operator to do differently.
- ✓Repeatable joint: same dose, same cure, same torque on every fastener.
- ✓Documented quality: ISO 9001:2015 system, lot traceability, certifications shipped with every order.
Same bolt. Same coating. Every time.
Consistent application is the quiet but decisive advantage of pre-applied. It’s the reason engineers can write a single torque value on the print — and trust that the joint will hit it.
Predictable torque
When dose is constant, friction is constant. When friction is constant, the bolt clamp-load matches the torque value the engineer specified.
Reduced warranty risk
Bolts that loosen in service are one of the most expensive warranty failures because they’re hard to recreate in the lab. Consistent application removes the variable.
Audit-friendly
Lot traceability and material cert documentation come from Bradley with the parts. The QA paperwork that’s usually a scramble at audit time is already on file.
Better OEE
Pre-applied removes a station-level operation from the line. Less cleanup, less variation, less rework — all of which roll up into higher Overall Equipment Effectiveness (OEE), the metric most manufacturing engineers use to measure line efficiency.
Reusability where it matters
Some chemistries (Bradley Nylon Patch, Loctite Dri-Loc 200/204) retain locking force after disassembly. Service-friendly without sacrificing security.
Less waste, less mess
No bottles to dispose of, no solvent wipes, no half-cured residue on jigs. Cleaner cell, fewer haz-mat manifests.
How pre-applied threadlockers actually work.
Most threadlockers are anaerobic — they cure in the absence of oxygen and in the presence of metal ions. Pre-applied versions package that chemistry into microcapsules bound to the fastener thread, ready to activate during assembly.
The five-second story
A pre-applied threadlocker is a dry-to-the-touch coating on the bolt thread. Microscopically, it contains tiny capsules of unreacted resin and a separate activator. When the mating thread shears the coating during assembly, the capsules rupture, resin and activator mix, and the mixture cures anaerobically into a strong polymer that fills the thread gap.
Because the chemistry only activates when threads engage and air is excluded, a coated bolt can sit in inventory for months without curing. Once installed, the joint develops full strength within 24 hours at room temperature.
The result is a thread joint with continuous polymer fill rather than the metal-on-metal contact that vibration normally exploits. That’s why pre-applied locking is dramatically more vibration-resistant than relying on torque alone.

Bare fastener threadCleaned, degreased, ready to coat. Bradley does not coat oily or contaminated parts — we reject or pre-clean first.
2
Carrier film depositedA thin polymer film is applied to the active threads. The film holds the microcapsules in place and protects them from premature shear.
3
Microcapsules embeddedTiny spheres of resin and activator are suspended within the film. The bolt is now “dry to the touch” and stable in inventory.
4
Installation & capsule ruptureMating threads shear the film. Capsules rupture; resin and activator mix.
5
Anaerobic cureIn the absence of oxygen and the presence of the steel substrate, the resin cures into a tough thermoset polymer within ~24 hours.
6
Locked & sealed jointContinuous polymer fill between thread crests resists vibration loosening; the thread is also fluid- and gas-tight.
