or embedments (e.g., resulting from fatigue, corrosion, inadequate installation, vibration, water hammer, or earthquake) should be emphasized in the installation procedures. 2. Procurement and Quality Assurance a. The applicant's overall QA program, including provisions for procurement, inspection, and testing of threaded fasteners, is reviewed by the HQMB as described in SRP Chapter 17. b. Guidance for detecting substandard or counterfeit threaded fasteners is provided in EPRI NP-5652, "Guideline for the Utilization of Commercial Grade Items in Nuclear Safety Related Applications (NCIG-07)," as endorsed by NRC Generic Letter 89-02, "Actions to Improve the Detection of Counterfeit and Fraudulently Marketed Products," and NRC Generic Letter 91-05, "Licensee Commercial-Grade Procurement and Dedication Programs." (1) Actions for detecting substandard or counterfeit products, including threaded fasteners, should be described in the applicant's procurement program. (2) If threaded fasteners are obtained as commercial-grade items, the fasteners should be dedicated for use in safety-related applications DRAFT Rev. 0 - April 1996 3.13-10 in accordance with the guidance offered in Generic Letters 89-02 and 91-05. c. The applicant's programs and procedures should include appropriate methods to verify threaded fastener attributes such as: (1) Pertinent fastener dimensions (e.g., diameter, head height, width across corners, width across flats); (2) Marking; (3) Plating or coating; and (4) Material properties (e.g., strength, chemistry, hardness, corrosion properties, surface condition). These attributes should be verified by visual inspection and testing in accordance with a documented sampling plan. d. Sections NB-2610, NC-2610, and ND-2610 of the ASME Code describe the so-called "small products exclusion," which exempts bolting material (including studs, nuts, and bolts) from certain QA provisions. It should be noted that threaded fasteners must meet the remaining Code
