Shear-Loc Products, based in Laguna Hills, California, has specialized in manufacturing the Original Quality Instant Thumbscrew since 1969. The company offers a unique conversion process—turning standard socket head cap screws into instant thumbscrews through the Shear-Loc method, presenting customers with three product options: knobs formed onto customers’ own screws, complete thumbscrews ready for use, and knob kits to maintain a ready supply. This flexibility supports research and development, maintenance, and machine shop applications by enabling rapid production of portable or quickly adjustable fasteners. Serving a plastics manufacturing niche, the firm emphasizes a cost-effective approach to producing ready-to-use thumbscrews and related components. The operation is modest in size, reflecting a specialized, niche-focused supplier within the broader fastener and plastics industry.
