Detailed description
Product Overview
The PF11MW-M4-1-2BL captive panel screw is a floating panel fastener with an M4 x 0.7 thread and a black knurled knob. Its captive construction keeps the screw with the removable panel when it is disengaged from the mating thread. The floating design accommodates alignment variation between the panel fastener and the mating hole.
This listing covers the PF11MW series, shank code 1, screw length code 2 and BL black version. Select the complete designation rather than an M4 thread alone: the mounting geometry, screw reach and operating clearance must suit the assembly.

The catalog identifies its dimensions as manually measured reference data. Use an approved product drawing or sample to confirm the final fit before preparing production panels.
Selection and Assembly Checks
Review the panel opening, thickness and retention arrangement together. A matching M4 thread does not establish that a different captive screw will fit the same panel preparation. Check the mounting dimensions against the PF11MW drawing and allow room around the knob for access.
Check screw engagement in the fastened position and clearance in the released position against the complete panel stack. The listed minimum float is a catalog value; it should not be converted into a guaranteed radial or diametral misalignment allowance without the corresponding drawing definition.
The product image shows a black knurled knob, a silver-colored sleeve and separate washers. Use the specified assembly arrangement when selecting the fastener and its accompanying hardware.
Frequently Asked Questions
Does length code 2 mean the screw is 2 mm long?
No. The number 2 selects a catalog configuration, not a 2 mm physical length. For PF11MW with an M4 thread, code 2 has a nominal G dimension of 8.89 mm; code 1 has a nominal G dimension of 7.37 mm. Compare the drawing reference and required reach before substituting one code for the other.
Does BL specify a black coating on every component?
No. BL identifies the black version, and this product is shown with a black knob and silver-colored components. The color code alone does not specify a coating process, coating thickness or corrosion rating. Include any mandatory finish or environmental requirements in the quotation request.
Should the two washers shown in the image define the assembly or order quantity?
No. A product photograph is not an assembly drawing or packing specification. Confirm the required washer arrangement and supplied kit contents for PF11MW-M4-1-2BL when ordering, rather than assuming that both visible washers must be fitted in every application.
