CLARENDON SPECIALTY FASTENERS, INC.

Clarendon Specialty Fasteners, Inc. specializes in the precision manufacturing of high-integrity fasteners for defense applications, including self-locking nuts, plain nuts, socket head cap screws, and close-tolerance bolts. The company’s technical expertise lies in producing mission-critical hardware that meets stringent military specifications, with a focus on materials compatibility, dimensional accuracy, and anti-loosening mechanisms essential for aerospace, naval, and ground vehicle systems. Their capability in self-locking nut designs—particularly plate, extended, and hex configurations—demonstrates deep familiarity with retention standards such as MS, NAS, and AN, ensuring reliable performance under vibration and thermal cycling. The firm’s ability to consistently deliver complex fastener geometries on tight schedules underscores a refined production process grounded in forging, threading, and surface treatment technologies. The company maintains an exclusive relationship with the Department of Defense, supplying mission-essential fastening components across multiple service branches. Their contracts consistently involve ordnance, aircraft, and vehicle subsystems where failure is not an option, indicating a trusted position within the DoD’s supply chain for hardened mechanical assemblies. Clarendon’s primary industry focus is in the manufacturing of bolts, nuts, screws, rivets, and washers (NAICS 332722), with supplementary capability in nonferrous forging (NAICS 332112). This positions them as a niche supplier of specialized metal fasteners for high-reliability defense platforms, serving as a tier-two or tier-three enabler for prime contractors requiring certified, low-volume, high-precision hardware. As a small business structured as a 2L entity based in Long Beach, California, Clarendon operates with agility and responsiveness tailored to government procurement cycles. While currently holding no formal government certifications, their consistent performance on defense contracts reflects operational discipline and adherence to defense quality standards, including AS9100 and ISO 9001 equivalents. Their geographic proximity to major defense hubs enhances logistical responsiveness to military logistics and repair networks.
