PSC 5305

Overview

The Product Service Code (PSC) is a uniform taxonomy the U.S. government uses in FPDS and SAM.gov to classify what is bought so spending can be tracked, analyzed, and reported. PSCs are maintained through the PSC Manual on Acquisition.gov and are required data elements on federal contract actions. ¹

PSC 5305 identifies “Screws” as a product classification within the hardware commodity family. Agencies select this PSC on contract actions when screws are the predominant end items being procured, consistent with PSC Manual guidance for product coding and FPDS reporting. ²

What this PSC covers

• Commercial- and military-specification screws used as mechanical fasteners across equipment and platforms, recorded as product buys. ²
• Purchases where a variety of screw types (e.g., different head, drive, or material) are supplied, provided screws are the predominant items on the action. ²
• Replacement or replenishment of screw stock for maintenance, repair, or production activities when the deliverables are screws. ²
• Screw assortments or kits classified to 5305 based on the PSC Manual’s “predominant product” rule for mixed-item buys. ²
• Hardware items designated by item name as screws rather than bolts, studs, rivets, or other fasteners; adjacent PSCs should be used for those other families. ²
• Environmental attribute reporting for screw purchases, when applicable (e.g., recovered content), via FPDS data element 8L. ²

FPDS coding notes for product buys

• The PSC is entered in FPDS as data element 8A; for mixed items, select the code for the predominant product. Apply environmental attributes (if any) under FPDS data element 8L in accordance with the PSC Manual. ²

Version/status context

• The April 2025 PSC Manual lists current product codes and reflects recent updates; no change to 5305 is identified in that release’s product-code summary (activation noted only for PSC 9105). ²

Frequently asked questions

• What does PSC 5305 represent in federal procurement?

  • It is the product classification for screws. It is used on contract actions when screws are the deliverable items, recorded in FPDS/SAM as the required “Product or Service Code” for product buys. ²

• How should mixed hardware orders with multiple fastener types be coded?

  • The PSC Manual instructs agencies to choose the code for the predominant product. If screws are the majority, use 5305; otherwise select the code matching the predominant fastener family (e.g., 5306 for bolts). ²

• Does PSC 5305 map to a specific NAICS code?

  • Not specified by official sources. NAICS assignment is solicitation-specific; the PSC Manual does not prescribe one-to-one PSC–NAICS mappings. ¹

• Are environmental or sustainable acquisition attributes reported for screw purchases?

  • Yes. When applicable, contracting officials report environmental attributes (e.g., recovered content, biobased, energy efficient) using FPDS data element 8L in addition to the PSC entry. ²

• Were there recent scope changes to PSC 5305?

  • The April 2025 PSC Manual change log lists no scope edits to 5305; the only product-code activation in that release is PSC 9105. ²
