STAINLESS STEEL HEXALOBULAR PAN CHIPBOARD SCREWS FULL THREAD

Hexalobular Pan Chipboard Screws Full Thread — A pan head gives a wider, flat-topped bearing surface than a countersunk head and sits proud of the board rather than sinking into it, which suits fittings with plain clearance holes or applications where spreading load matters more than a flush finish. This full-thread version drives the thread the entire length of the shank, giving consistent grip when fixing directly into a single thickness of chipboard or particleboard — general assembly, brackets, and fittings without a separate top component to clamp are the typical uses, in contrast to the part-thread pan head version, built specifically to draw a top component down onto the board. Hexalobular drive is the reason to specify this over the Pozidriv equivalent: it offers better resistance to cam-out and higher torque handling, which suits sustained power-tool use in production or trade fixing work far better than a cross-recess does over a long run of screws. Chipboard screw thread geometry generally follows the DIN 7505 specification, using a coarser, sharper thread flank than a wood screw thread, since particleboard's compressed particles need the thread to cut and grip mechanically rather than wedge between long fibres the way it would in solid timber. Grade selection follows the same pattern as elsewhere in the chipboard range: A2 (304-equivalent) is the right, cost-effective choice for the large majority of chipboard assembly, which is almost entirely indoor furniture and fittings work. A4 (316-equivalent) is worth the extra cost only where board-based fixtures sit in persistently damp or humid conditions, since A2 could eventually show surface corrosion there that A4 resists. Choosing gauge and length should reflect the fitting's load and the board's thickness, ensuring full thread engagement without the screw's point breaking through a thinner panel's far face.

FAQs
What's the benefit of a pan head over countersunk here?
A pan head gives a larger, flat bearing surface and sits proud rather than sinking flush, suiting fittings with plain clearance holes and spreading clamping load over a wider area.

How does this compare to the part-thread pan head version?
This full-thread version is threaded along the whole shank for grip into a single board thickness; the part-thread version has a plain shank section that lets it clamp a top component down onto the board beneath instead.

Why hexalobular rather than Pozi drive on the pan head range?
The hexalobular recess offers better resistance to cam-out and higher torque handling than Pozidriv, which suits sustained power-tool use in production or trade fixing work.

Does this screw need a clearance hole?
Only in a separate component being fixed with a plain hole, if there is one — the screw itself doesn't require a countersunk recess since the pan head sits proud rather than flush.
