Frequently Asked Questions
Do I have to buy in bulk?
Most products are available in small packs starting at 5 pieces, with automatic volume discounts as quantity increases. Some products are marked Bulk-Only — those ship in single supplier packs at bulk pricing and may become available in smaller packs as our inventory expands. Look for the Bulk-Only badge on the catalog and product pages.
What material are your fasteners?
We carry steel, stainless steel (18-8, 304, 316), alloy steel, brass, and specialty materials. Each product listing shows the exact material, grade, and finish.
How do I find the right size?
Use the catalog filters to search by diameter, thread pitch, length, and head style. Each product page lists full dimensional and technical specifications.
Do you offer volume pricing?
Yes. Every product page shows tiered pricing. The per-unit cost decreases automatically as you increase the quantity.
What is your return policy?
We accept returns within 30 days of delivery for unused items in original packaging. See our returns page for full details.
