About this category

304 stainless truss head cross-recess screws in inch sizes, #8 to 1/4" thread and 1/4" to 3" long. The head form is the same as the metric version - wide and low, giving a large bearing area for thin sheet, plastic and oversized holes - the only difference is the sizing system. For US-built equipment and sheet metal assembled to inch drawings.

Standards ANSI B18.6.3

How to choose

• Inch and metric truss heads look almost identical but the pitches differ - mixing them strips threads.
• You choose this head for its diameter, so check it covers the hole edge.
• A low head means a shallow recess and low torque limit; turn power drivers down.
