A custom fastener is back on your desk. Its price has climbed, the next production order is approaching, and your team is preparing to send the drawing to another supplier. Getting a competitive quote matters. Before sending it, though, it is worth asking what is driving the cost of the part itself.
A custom feature, an extra manufacturing step, or a finish requirement may deserve a closer look. Fastener cost reduction can begin with understanding those details and determining whether a simpler design, a standard part, or an approved common part could meet the application's requirements at a lower overall cost.
At Field, we help purchasing and engineering teams investigate those possibilities together. The starting point is understanding how the part is made, where it is used, and what it needs to do.
Understand the features behind the price
A special head shape, tight tolerance, or multi-piece assembly may serve an important purpose. Reviewing why each feature exists helps your team distinguish necessary requirements from opportunities worth evaluating. A feature might provide installation clearance, support a particular assembly method, or satisfy a customer specification. Understanding that function gives engineering a basis for considering alternatives.
Material and finish choices also affect performance, availability, and cost. Before comparing options, confirm the strength, corrosion resistance, temperature performance, and compatibility the application requires. A drawing may have carried specifications through several product revisions, making it useful to check whether those choices still reflect the current application.
Our engineers' guide to choosing the right fastener finish explains considerations to bring into that review. Any proposed alternative still needs the appropriate evaluation and approval.
What a design review can uncover
In one customer project, a custom cap nut was both costly and difficult to source reliably. Field redesigned the component so it could be cold formed using fewer manufacturing processes and specified a finish to meet the application's corrosion requirements. The published case estimates approximately $346,000 in annual cost savings from the proposed redesign.

The opportunity came from examining the design and manufacturing process alongside the customer's requirements. That is a useful question to bring to your next sourcing conversation: could a different way of making the part help meet the cost target?
Look for opportunities to simplify part numbers
Fastener standardization identifies where an approved common part can serve specific applications. When requirements align, consolidation can reduce the number of different items your team purchases, stocks, and manages. Begin with one part family or assembly area and compare drawings, actual usage, and installation requirements. Similar-looking parts may serve different purposes, so the application needs to guide the decision.
An onsite Field VMI representative found one such opportunity after noticing eight zip-tie sizes on a single production line. Working with the customer's engineering team, Field helped eliminate four zip-tie items. The case reports $39,670 in savings.

That example shows why purchasing, engineering, and the people managing replenishment all have a role in the review. Observations from the production floor can help identify opportunities that deserve a closer technical evaluation.
How Field helps move a change into production
Our Value-Added Engineering services include print reviews, assembly line reviews, product teardowns, and part-consolidation evaluations. Testing and documented recommendations give your team something concrete to assess before deciding whether to move forward.
A proposed change needs a clear evaluation and transition plan. Purchasing, engineering, quality, and operations should agree on application requirements, samples and testing, approval responsibilities, and how existing stock will be managed. Tooling, work instructions, replenishment settings, and the first production run may also need attention. Your designated engineering and quality authorities approve changes through your procedures, including any required customer approvals.
Give the savings a clear starting point
Record current part cost, usage, and relevant processing or assembly expenses, then compare the alternative using the same volume and scope. Include testing and transition costs so your team can assess the implementation as well as the proposed benefit.
Keep the benefits clear: time returned creates capacity, inventory reductions may release cash, and recurring expense savings require an actual expense reduction. After implementation, check results against the baseline. Our October article, The Supplier Quote Is Only Part of Your Fastener Cost, explains the broader cost comparison.
Start with one part worth reviewing
You do not need to review the entire bill of materials at once. Choose a costly custom component, a part family that keeps growing, or an assembly step your team has been working around. Tell us what the part needs to do and what is making it difficult to buy, manage, or use.
There are better ways to save. Talk with Field about your part or part family, and we can help determine what information is needed and which opportunities are worth evaluating.
