When managing structural bolting procurement, finding the right DTI washer for sale involves more than simply looking at the base unit price. Buyers must understand the various cost factors that impact ASTM F959 bulk pricing and overall project budgets. From surface finishes and material grades to advanced visual tension indicators, every specification influences the final cost. At FULLERKREG, we aim to provide transparent pricing and reliable supply for construction projects worldwide. Whether you are looking to buy DTI washers online for a small repair or need high-volume direct fulfillment for a major infrastructure project, this guide will help you navigate the purchasing process. Explore the FULLERKREG ASTM F959 DTI washer collection to review your options and secure the best value for your structural connections.
What Affects DTI Washer Price?
Bolt Diameter and Washer Size
Larger bolt diameters require significantly more raw material and heavier forging capabilities, which naturally increases the manufacturing cost and unit price of the washer.
Type 325 vs. Type 490
Type 490 DTI washers require specialized, advanced heat treatment to achieve higher hardness levels necessary to match A490 structural bolts. This extended thermal processing makes them slightly more expensive than Type 325 washers.
Surface Finish (Plain, Mechanically Galvanized, Hot-Dip Galvanized)
Plain finishes are the most economical option. Adding protective coatings like mechanically galvanized or hot-dip galvanized layers adds secondary processing time, logistics, and material costs.
Standard DTI vs. Squirtern DTI
While Squirtern DTI washers have a higher initial unit price due to the proprietary silicone compound embedded in the protrusions, they drastically reduce field inspection time and labor costs on the job site.
Order Quantity
Like most structural fasteners, DTI washers benefit heavily from economies of scale. Purchasing in case, pallet, or container quantities yields the most aggressive bulk pricing discounts.
Certification and Documentation
Providing comprehensive Material Test Reports (MTRs) and maintaining strict lot traceability requires rigorous QA/QC overhead. This ensures the structural integrity and compliance of the parts you are buying.
DTI Washer Price Ranges by Specification
| Bolt Diameter | Type 325 Plain Finish | Type 490 Plain Finish | Mechanically Galvanized | Hot-Dip Galvanized |
|---|---|---|---|---|
| 1/2" – 5/8" | $ | $$ | $$ | $$$ |
| 3/4" – 7/8" | $$ | $$$ | $$$ | $$$$ |
| 1" – 1-1/4" | $$$ | $$$$ | $$$$ | $$$$$ |
| 1-1/2" | $$$$ | $$$$$ | $$$$$ | $$$$$+ |
Note: The table above represents relative price scaling. Please contact FULLERKREG for exact pricing based on current steel indices and your specific volume requirements.
Squirtern DTI Washer Pricing Considerations
| Cost Factor | Standard DTI Washer | Squirtern DTI Washer |
|---|---|---|
| Unit Material Cost | Base price | Premium price |
| Inspection Labor | High (Feeler gauge required per bolt) | Low (Visual confirmation) |
| Inspector Training | Extensive | Minimal |
| Inspection Time per Bolt | 30 - 60 seconds | 1 - 3 seconds |
| Rework Risk | Moderate (False readings possible) | Very Low |
Although the initial procurement cost is higher, using Squirtern DTIs can reduce the total installed cost of structural bolting by 15–25% on large projects by virtually eliminating the bottleneck of feeler gauge inspections.

Frequently Asked Questions
How much do ASTM F959 DTI washers cost?
The price varies based on bolt diameter, grade (Type 325/490), finish, and order volume. Plain finish smaller diameters are the most economical, while large, galvanized Squirtern DTIs carry a premium.
Are Squirtern DTI washers more expensive than standard DTIs?
Yes, the unit cost is higher due to the integrated silicone visual indicator. However, they frequently reduce total installed cost by significantly lowering inspection labor hours.
Does FULLERKREG offer bulk discounts?
Absolutely. We offer scalable bulk pricing across case, pallet, and mill-direct container tiers for significant procurement savings.
What is the minimum order quantity?
For in-stock standard items, the minimum order is typically one box. For custom finishes or special runs, standard mill MOQs will apply.
Can I get a formal quote for a DOT or industrial project?
Yes, our team specializes in providing comprehensive quotes for large infrastructure projects. Email your RFQ to sales@fullerkr.com.
How fast can DTI washers ship?
Currently, orders are shipped 6-8 weeks after confirmation. Our inventory is currently being stocked. Once fully stocked, standard plain and mechanically galvanized DTI washers can generally ship within 24-48 hours. Transit times vary by location.
