At the \u003cstrong\u003eDIY Hardware Store\u003c\/strong\u003e, our Whitworth-sized zinc-plated machine screws are available for the legacy engineering, classic vehicle restoration, and vintage machinery maintenance applications where metric thread screws are not compatible.\u003c\/p\u003e\n\n\u003cp\u003eThe British Standard Whitworth (BSW) thread form uses a 55-degree thread angle and specific thread pitches that are entirely different from the 60-degree ISO metric thread. A metric screw will not engage correctly with a Whitworth-threaded hole, and vice versa - using the wrong thread risks cross-threading, thread stripping, and fastener failure. For anyone working on pre-metric British motorcycles, classic cars, vintage agricultural machinery, or old British industrial equipment, Whitworth screws remain an essential stock item.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in the most commonly used BA and BSW thread sizes at the DIY Hardware Store, in zinc-plated steel in the countersunk and pan head formats most frequently needed for legacy machinery maintenance.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eBSW (British Standard Whitworth) thread form - 55 degree angle\u003c\/li\u003e\n\u003cli\u003eNot compatible with metric threads - do not interchange\u003c\/li\u003e\n\u003cli\u003eEssential for pre-1970s British machinery and vehicles\u003c\/li\u003e\n\u003cli\u003eUsed in classic car, motorcycle, and vintage machinery restoration\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel in standard BSW and BA thread sizes\u003c\/li\u003e\n\u003cli\u003eCountersunk and pan head formats available\u003c\/li\u003e\n\u003c\/ul\u003e","products":[{"product_id":"whitworth-machine-screw","title":"Whitworth Sized Machine Screws Zinc Plated (Sold as singles)","description":"\u003cp\u003eWhen precision and historical accuracy are paramount, these Whitworth Sized Machine Screws are your go-to fastening solution.
