UNSPSC 31163303: Ball stud

Studs with a spherical or semi-spherical configuration at the end opposite the threads to facilitate pivoting and/or rotation.

UNSPSC 31163303 Ball stud is a Commodity code that encompasses fastening components and threaded products purchased by state and local transit and transportation authorities. Recent opportunities show state and local governments buying ball studs as part of broader threaded fastener and fastening-supply packages—bolts, cap screws, lock nuts, washers, threaded rods, socket cap screws, machine screws, rivets, and hose clamps—along with unrelated consumables like rubbing alcohol. The Orange County Transportation Authority (OCTA) IFB 250199 for threaded products and fasteners is the most relevant recent opportunity under this code, soliciting a three-year supply contract with an estimated value of $150,000 covering 154 fastener line items delivered to two facilities in California. Transit authorities are the primary issuing bodies visible in recent activity under this code. The fastener procurements typically impose North American sourcing requirements (USA, Canada, or Mexico), high-strength Grade 8 (10.9 metric) specifications, and proof of compliance through ISO 17025 laboratory certifications or MilSpec documentation. Contractors must support monthly scheduled deliveries, respond to urgent requests within 48 hours, maintain semi-annual inventory reports, provide barcoded labeling, and accept return of surplus inventory with credit.

Activity under this code is concentrated in California, with OCTA (Orange County Transportation Authority) as the standout repeat buyer visible in recent opportunities. The OCTA IFB 250199 had a response deadline of March 16, 2026, with award anticipated April 6, 2026, and includes a Disadvantaged Business Enterprise goal (percentage to be determined), prevailing wage requirements under Davis-Bacon and California Labor Code, and standard commercial general liability insurance of $1 million per occurrence. The code shows limited geographic spread in recent postings; only California opportunities are visible for fastener procurements aligned with the commodity scope, while unrelated consumable procurements (rubbing alcohol) from the Dallas Area Rapid Transit Authority distort the category's relevance. Pricing on the OCTA fastener contract is firm fixed unit price on an F.O.B. destination basis with no price increases permitted over the three-year term.
