The Draper 19 Piece 20mm Drive Go Through Socket Set is a professional socket set designed for working with extended threaded fixings that exceed standard socket depth limitations.

Edge-driven socket design improves grip on fastener flats whilst reducing the risk of rounding. Three extension bars provide additional reach flexibili
