Geometry
Evaluate material movement, feature sequence, head-to-shank transitions, and areas that may resist forming.
Cold Formed Fasteners
Cold Formed Fasteners Engineered for Production
Eversteel Global supports custom cold formed fasteners through drawing review, multi-stage forming, tooling and die design, thread rolling, heat treatment, surface treatment, inspection, and production planning.

Direct Answer
What are cold formed fasteners?
Cold formed fasteners are parts shaped from wire or another starting form through controlled deformation, typically at or near room temperature. Cold heading commonly refers to forming head features, while cold forming is the broader process category; cold forging is often used as an industry term, but the exact process description should match how the part is made.
Manufacturing Scope
A production-ready fastener depends on coordinated decisions.
Each requirement is reviewed in context before tooling or production decisions are made.
Tooling
Plan die access, forming stages, load direction, and tool support around the part geometry.
Threads & Secondary Work
Coordinate thread rolling and any limited machining with heat treatment and finishing requirements.
Production Control
Define sampling, inspection, validation, and process controls around the drawing and application.
Engineering Review
When should an engineer consider cold formed fasteners?
Cold forming becomes a strong candidate when the geometry, material, tolerance strategy, and production demand support repeatable forming. It is not automatically the right process for every feature or volume.
Request a manufacturing review- The part can be formed without material-flow conflicts or inaccessible tooling features
- Production demand can justify dedicated tooling and process development
- Critical tolerances are assigned to functional needs rather than applied everywhere
- Secondary operations are limited to features that cannot be produced efficiently in the forming sequence
- Material and downstream heat or surface treatment requirements are considered early
- Validation and inspection requirements are defined before production release
Development Process
From fastener drawing to repeatable production
The sequence is adjusted to the drawing and customer program; no unverified lead time or production quantity is assumed.
Requirements
Clarify application, drawing, quantity, material direction, and quality expectations.
Feasibility
Review geometry, forming stages, tolerances, tooling access, and risk.
Process Plan
Coordinate forming, thread rolling, secondary operations, heat treatment, and finish.
Tooling
Develop tooling after the manufacturing direction is accepted.
Validation
Sample and inspect against the agreed drawing and project plan.
Production
Control the approved sequence for consistent manufacturing.
Applications
Engineering support for industrial applications.
Application context helps determine which geometry, material, quality, and production decisions are critical.
Quality & Validation
Quality requirements are planned with the manufacturing route.
Quality planning can include ISO 9001 and IATF 16949 systems, PPAP support, sampling, validation, process controls, and inspection requirements defined for the project.

Common Engineering Questions
Direct answers for engineers and procurement teams evaluating a custom manufacturing project.
Are cold forming and cold heading the same?
Cold heading usually describes forming a head or upsetting material, while cold forming is the broader family of processes that can create multiple features through staged deformation. The correct term depends on the actual operation.
Can every machined fastener be converted to cold forming?
No. Geometry, material, tolerance, undercuts, quantity, tooling, and secondary operations determine feasibility. A DFM review is required before choosing the process.
Does cold forming eliminate secondary machining?
Not always. It can reduce machining when features are formable, but some bores, undercuts, precision surfaces, or other requirements may still need secondary work.
